Sure, There's lots of problems with stacking so much damn spirit. The Most egregious being that you are completely neutering your Heals when you do so, Im not just talking a little, but by like 10% or maybe more. Our secondary Stats have FANTASTIC Synergy, and NONE OF THEM SHOULD BE IGNORED. Ill just start by explaining My weights and why I chose them
Spirit to 6K> Haste to 5700>Mastery to 50% (about 5100ish)>Crit
Spirit & Crit- 100 Points of Spirit is worth Approx 57 MP5 When you are casting Healing Wave, & Greater Healing Wave, 100 Points of crit is worth 42 MP5, Riptide and HS is 29.5 MP5, and Chain Heal is about 9.8 MP5. Lets say you are using a good Mix of these spells in your normal rotation (I tend to use HW a Lot as filler) Ill be conservative and say With my mix of heals 100 Points of crit is going to be around 25 MP5. So In PURE REGEN TERMS ONLY, 2 Points of Crit=1 Point spirit (almost). Now then Factor in the fact that Crit is Probably your second best throughput stat on top of it (haste is slightly better), and I wonder why a lot of shamans are ignoring Crit. Instead of taking 10000 Spirit, Take 6000, and add 4000 crit, Its like Having 8k Spirit anyway (which is a lot), with the bonus of having 4000 crit!
I will have NONE of the argument that More Spirit helps your mana tide and conversely your other healers. OTHER HEALERS ARE NOT BALANCED AROUND YOUR MANA TIDE, While shamans are balanced around the fact that they have Mana tide available. It is a Bonus, they get what they get, Period. You need to be thinking about your character alone while you reforge
Haste- I also see a lot of Shaman Completely Ignoring Haste Past 871. This is horrible. Ill give you a concept I never hear people bring up when they argue against haste. NOT HAVING A DECENT AMOUNT OF HASTE CAUSES YOU TO OVERHEAL MORE. Yes its true, while your slow heals are taking forever to land, one of your other healers has likely already topped off that person. Druids have Rejuv, wild growth, swiftmend and Lifebloom is a crazy fast HoT. Pallies have instant heals. Shaman have.....cast times. Also, take a look at this spreadsheet
http://www.totemspot.com/vb/entry.php?b=41 Tjose are your breakpoints, I dont know about you, but I want an extra tick of Healing Stream and Healing tide, Yes if you hit that Number EXACTLY lag can eat up that extra tick, so go over it, go over it so much that you reach the next breakpoint, Riptide. I dont know about you guys, but riptide is always in my top 3 healing done, an extra tick is a No brainer, Again, Go over the cap to account for lag, 5700 will do the trick, this puts you at about 25% raid buffed. Now your heals have some teeth
Mastery-Not Much to say here, Get it to 510oish (about 50%) then reforge out of it. Mastery soft caps at 50%
If youre doing all of this and STILL having mana Issues, heres some more stuff to try
Glyph of Totemic recall- This Glyph is really really powerful, if you use it right you can get back well over 100k more Mana back a fight than Unglyphed, Simply recall your Healing stream and Elemental totems at the last second, youll have gotten the full (or almost) the full benefit of them for a cost of ZERO mana. Healing stream totem is expensive....14.1K mana thats 2/3 the cost of a healing rain, its not cheap, Fire and Earth elementals cost over 16k Mana, again, theyre expensive! So make sure youre recalling them
Glyph of Water Shield-Learn Which fights favor the Glyph over thse which dont. The difference in mana Can be huge.
Glyph of Telluric Currents- Good Synergy with Unleashed lightning. Good for sneaking in some lightning bolts during movement. Lightning bolts provide about 240 MP5 with this glyph while you are casting them.
Glyph of healing wave- If you have nothing to glyph for a certain fight, this is free extra healing, take it and dont apoligize
And finally the last thing I want to touch on is The Glyph of Riptide. I HATE GLYPH OF RIPTIDE WITH A PASSION. Why? The Best part of riptide is its Initial Heal, it has great synergy with our single target heals. The HoT on Riptide is actually kinda weakish. So what the Glyph essentially does is turn riptide into a Weak Rejuv. Spamming riptides is a sure way to Go OOM and find yourself lagging behind your other healers. Instead, Use the cooldown on riptide to your advantage, Instead of spamming riptide and sitting on stacks of tidal waves. Cast riptide and USE those stacks, Tidal waves is meant to be USED Not sat on! A good simple rotation of Riptide-(G)HW-(G)HW-Choose your spell-Riptide is extremely effective, and heals a surprisingly high number of members of your raid in those 6 seconds.
Now if the fight is Just so heavy movement that you cant get a heal in edgewise, MAYBE i will glyph riptide, But then Ill come to my senses and just use SWG effectivley and unglyph it again =)
