Hello this posts will consist of two parts. The first is Blizzards failed promise on more smooth out raid damage. And the second part will consist on how to fix disc. Ofcourse keep in mind all of this is my opinion, and I'm interested to see how you look at it.
Unkept promise
Blizzard stated that during the development of WoD they wanted raid damage to smooth out, instead of bursts, where you needed to heal the person back up asap. Let's take a look at BRF, a great raid, half of the raid is well done in concern of smooth our raid damage.
But let's take a look where fights have a mandatory or close to mandatory disc. Gruul, maidens, furnace, and blackhand. The reason disc is mandatory here is because it all consist of burst damage. Why did blizzard not smooth this damage out as was their intent? I personally feel blizzard could have turned alot of those high damage instant into Dots.
Dots Or well know as damage over time is pretty much the equivallent of smooth out raid damage. For example at gruul, they could've made the impact slice way less straight up. And instead made the 30 second debuff a Ramp-up DoT. I feel this change would still make disc strong on this fight but less mandatory. I also feel it wouldn't impact the healing fun level for this boss. And infact think they it might be more enjoyable for other healers.
Same for maidens, turn the damage from blade dash into a dot, disc would still be powerfull, but not mandatory.
Now I'm not vouching to turn every damage into a dot. But why if your intent is to smooth out raid damage, are there so few dots, and so many high instant damage abilities.
I feel disc would not lose alot of it's power here and it would make it more enjoyable for other healers. Blizzard also stated that with 20 man mythic they can expect to bring every class to the party. And it's fine to revolve a fight around disc, but it is mandatory on to many fights and above all It's not fun. Maidens imo is boring as hell.
One of the counter arguments could be that while disc has the shield up the target wouldn't need healing for some time, thus making it boring for other healers. While if there is a huge burst, even if most is soaked by the disc, targets would still needer sooner healing. The only thing changing is that the majority of the healing then comes at the end of the dot mechanic instead of instantly when the mechanic is present. Nor am I saying that they should be very long lasting dots either. If the DoT alone is 5 seconds. Then disc would already lose some preshield power.
Short version Dots would smooth out raid damage more and make disc less mandatory.
How to fix Disc
Next to the fact[Citation needed] that disc is currently really strong, it's also mindblowingly boring. Here are some ideas that I feel would make the spec much more enjoyable, use more spells. But the downside is it is more proc dependent
First, nerf Pw: S around 20-25% (Numbers are ofcourse debatable)
Secondly, casting Penance has a 30% chance to make your next PoH cost 50% less mana and have a 33% lower cast time.
Thirdly, Whenever PoM heals a target there is a 15% chance to make your next Holy nova heal 100% more and has it's range increased to 30 yards.
The main idea here is more synvergy wich promoted more different spells usage, instead of our current interesting pw: s spam. The downside is the proc dependent of it. However you could also make it a stacking buff, each time PoM heals a target Holy nova heals 20% more and has it's range increased by 5 yards. Or any of the likes.
I'm very interested to hear your opinion on this. The main reason I wrote this is because disc is currently so boring, I can't focus with it. You could litterly make a mouseovermacro for pw: s and bind it to the middle mouse. And just keep scrolling while watching the tele.
Small Holy rant
I'm fine with the fact the archimonde trinket is shit. But the way it is currently implented is just a massive insult. I also feel holy needs the disc passive to have 30% more healing on GH and FH. Hell we wouldn't notice the difference at all, yet is imo something holy dearly needs.
