More than ten months after my Lich King solo, I finally got Ragnaros - This was made possible the fact that his berserk wasn't an issue, lucky for me, since I lost so much dps rezzing my pet or stalling shots to keep mend pet up/burst adds when they spawned that I did only 75% of my max dps. So it was all about survival, hence the stamina flask, food, scroll and trinket. I did it with 491 ilvl gear, and it took me about 14 hours of tries to refine the strategy until I killed him before my last pet died.

Now, for the guide. This is a perfect challenge for any normal-geared hunter who enjoys soloing, all you need is time and money.
RAGNAROS HUNTER SOLOING GUIDE
I-Important points
First words
This fight is a unforgiving battle for survival, and only survival. So gear counts less than on other bosses: you will need health, lots of it, and it scales much slower than dps. Then, of course, the more dps you have the better, since the most difficult part of the fight is killing him before you run out of pets.
Preparation
For pets, you will need 5 beetles/turtles, tank specced. Make sure they are in defensive. You will also want to buff yourself with stamina - I personally used a stamina flask, scroll, food and a stamina trinket. I was so focused on survival I didn't really care about dps - usually delayed kill command, stacked focus or avoided cobra shot - to make sur I would use deterrence/mend pet/rez/fd precisely at the right time. So even 50K dps is enough.
I personally had 491 ilvl on this fight, but it should be possible with less.
For talent you will want Crouching tiger/hidden chimera , so you can rez your pet once every minute , binding arrow for transition phases and your usual talents. I used glyphs of animal bond and misdirection to maximize survivability and make sur my pet got aggro even when fd was on cooldown.
Basic principles
This fight is about pets. You have 5 pets. Ragnaros melees for 60-75K on pet and puts a stacking dot debuff. it goes without saying that your pet won't last very long. So, there are 3 things to know about pet management here.
Rezzing your pet: once every minute, you have deterrence up (unless you use readiness). That means that if your pet dies, you can rez it while taking only 1-2 melee hits. Important: if you are out of melee range and your pet dies, he will cast magma blast on you - and it will do an extreme amount of damage in 6 seconds (300K at least). There are 3 possible ways to rez your pet.
*He is about to cast sulfuras smash (less than 6 seconds): be right next to him, pop deterrence and rez pet, the mend pet and FD.
*He is really about to cast sulfuras smash (1 second or less): rez pet, pop deterrence, mend pet and FD
*He is not going to cast it: stand far from the boss (but still in melee range), pop deterrence, rez pet then spam click disengage to get out of melee range. Then mend pet and FD.
Pet switching: when your pet is about to die and you can't rez him, it's time to change pet. The best time to do it is during a smash - start dismissing 1,9 seconds before (or you will get a magma blast), summon new pet and send him in melee range. If you have to do it right now, make sure you are not in melee range - you will get at most 2 blasts, which hurts less than 2 melee hits. Also FD after the switch, so that you can go in melee range of the boss.
Destacking pets:a pet is usually dismissed with 5-10 stacks. The only way to destack him is to let him die then rez him (bad idea), or making transitions last longer and switch pets to destack them.
II-Phase by phase strategy
Phase 1
Bumps: Ragnaros will sometimes bump you if you're in melee range (can send you in a trap, interrupts rez), and his hand of ragnaros simply does damage, slowing your health regeneration, and makes you jump: it interrupts rez, but it is deflected by deterrence if and only if you're not casting rez at that time. If one of the 2 interrupts a rez, just reset and restart.
Magma trap and smash: magma traps will stay for all the fight, and you won't have the luxury of wasting a deterrence on them. So you want to stack them in a corner of the room. On every try but the kill, he always did them after a Sulfuras smash. So the goal is to know where you want to put the trap, move 10 yards to the right/left, and when he smashes go where you want him to put it.
Pet management: do not use more than two pets this phase. To achieve it with low dps,the best is to do the following pattern:
*pet 1: use cower on the pull. When he cast shell shield, check the timer on cower. Once it's at 15 second, you can use last stand if it's worth it (meaning: avoid overheal at all costs, you'll need every inch of healing here). Then reuse cower after the smash. Once he used magma trap, run to melee range. When your pet dies, rez him (see above for how), and use readiness before he dies again.
The rerez him. After that, you'll want to change pet at the next smash.
*pet 2: don't use last stand until the first death. Rez him, then you'll want to heal back to full before the transition. To do so, use last stand at the last possible moment with stampede, and finish the phase before your pet dies.
Transitions
You'll want to have bestial wrath up here - and use a bandage while he's casting splitting blow if needed.
*middle split: the hardest by far. You'll want to one shot a son near the hammer and use binding shot to slow the 2 nearest sons on the other side, use bestial wrath kill them and kill the 2 last - so that 3 sons will pass on a side and 0 on another. You won't have time to destack 2 pets, the best is to take your 1rst pet back so that last stand is up.
*side split: let the 2 nearest sons pass, and make sure you kill the 3rd son asap, then use bestial wrath to kill/damage the sons; making sure to slow them first then finish them. Binding arrow is best on the 5th or 6th son. The best way to destack pets is to dismiss your pet just before they spawn, summon the first one one, leave a son alive (but under 50%), then once the first one is at full health with no debuff, get the current one back. Kill the son once he's destacked. If done right, only 2 sons will pass and 2 pets will be destacked.
In the second phase 2, the low-gear strategy is to fd when the big adds spawn, the high-gear is to blow everything up If you get Ragnaros + adds, you'll have to use last stand + stampede.
Phase 2
Abilities: You won't get bumped anymore! This phase is the easiest. Ragnaros will now randomly blow up a third of his platform - don't stand in the fire. He will also cast molten seeds. When he does, immediately move near the boss, and your pet. The elemental melees quite hard, and you really don't want him alive when your pet is dead, so kill it quickly. Make sur not to send your pet on it until he has arrived in melee range.
Pet management: Here again, do not waste pets. The best thing is to rotate pet cooldowns, and rez him when he dies. He can last a minute, but it's tight, so use readiness if he dies too quickly. If readiness isn't up, use last stand to last the minute. If it isn't up, it's time to switch pets. Once the boss hits 45% and your pet is dying, use stampede + last stand and finish the phase with as much health as possible.
Phase 3
The final phase! You will want to have 4 pets destacked, and start the phase with one who still has last stand up. Because, this time, no rezzing. Rotate Cds, use last stand and switch before they die.
Meteors: they are exactly as fast as you are (remember you have aspect of the cheetah!), and spawn every 45 seconds. You want to put them at the back of the room. Make sure you fd pretty quickly, or they'll hit you and continue following you. If one starts doing that, you'll have to run while being in healing range of your pet but not reaggroing another meteor while avoiding the fire and smashes and pet switching becomes a lot harder. But then, had I killed him cleanly, it wouldn't have been as exciting for me.
In the end, stampede + last stand and buuurst!
Now you've solo'd Ragnaros, a perfect challenge for normal-geared hunters.
