You're one of those people I mentioned Funky in my previous post that hurry to comment anythung without you've read even the end of the sentence. Did I say SP sux? Did i say SP and Haste is not best shaman stats anyway or something like that or just opposite that SP always will be your primary stats and anyway even if you do not want it accumulate because as i know in the game just not exist higher item level items for casters or healers without Spell Power, but there exist item without Haste (all items with SP + Critical + Mp5s) or without Critical (all items with SP + Haste + Mp5s) or without Mp5s (all items with SP + Haste + Critical) or briefly Spell Power is constant stats for each item what you will receive like Intellect and Stamina.
This what i say only:
"Briefly if I have to summarize individually for myself, Critical strike raiting comes for me as one of the best stats for Restoration Shaman which is not affected by the various encounters as Haste raiting. If I need more Haste raiting I take it but I try to keep my Critical raiting on good level."
Tell me how to answer you at this after you even not bothered to read category STATS , especially Critical Strike? And you ask for math/simulation/analysis? Unfortunately i haven't pic to show you now but how you feeling 30% healing done from Ancestral Awakening from total my healing done on LK fight?
I will not mention even that on 10 man raids even in most situation Ancestral Awakening will be your main ability for AOE healing instead of Chain Heal because spreading of ppl and will be waste to use Chain Heal which will hit 1, 2 targets only, but probably you didn't read even this?
About Glyph for Healing Stream Totem is just pointless to waste glyph slot for it instead of glyphs where will benefit you much more and i will tell you why. As healer you will be putted in most of situation in group 5 with other healers. Anyway Healing Stream Totem is supposed to heal only your group members (not all raid) with really low amount of healing which even glyphed is less than amount of healing of your Earthliving. Really Healing Stream Totem itself can help you for some AOE fights like BQL, SIndragosa 2nd phace, LK in transition phaces (generally at all AOE situations) but tell me how much you will receive more with glyph? 100, 150 more of your Healing Totem for what? to heal additional a group from healers ?
I will give you situation - You are at BQL and boom shadow bolt flying toward you and you are on 20-30% hp. So you will wait your healing totem to fully hp you?, or you will waste 1 GCD and 1 spell cast to heal yourself or simple you can use for example glyph of Healing Wave, to heal someone else where you automatic will heal yourself and with situation of critical you will heal someone else via Ancestral Awakening. Or my simple question is which glyph you will replace for Healing Totem? CH, or Eartliving or HW? or which?
A conclusion, I can tell you from what I understood from your comments that you are a player who cares only about HPS and forget for most important things here. Every Shaman can burst 20k+ HPS easy, so what? Is not it more important outcome? Whether the raid will remain alive and the boss will be done?
Have a nice day my friend :)
