Is there anyone thats finding themself with a mana issue at 50? or can some points in Shaman be dropet in favour to add to Purifier tree and dropping Ageless ice?
If you are OOM'ing as a Cleric tank then you aren't doing it right. I literally NEVER run out of mana unless the mob(s) are mana draining me. I would hope you know as a Cleric that we DO NOT stack Dex/Str/etc that a Rogue or Warrior would have on their tanking gear, Spell Power is our Parry and forget Dodge, we just don't get much of it. Your stats are basically the same as any Cleric, except Crit is nearly useless to a tank. You should not be wearing Leather tank gear, pretty much ever and even the "tank" rings, essences and necks are up for debate as we gain our primary tank stat (Parry) from Wisdom (which is Spell Power to us).
Also you mention something about added physical damage output...why. First off something like 95% of Justicar tank abilities are spell damage, not physical and second adding 5-10% damage to already the lowest DPS output in the group/raid is completely wasted points. Spend those points in talents that help you tank better. And if it's a matter of better threat gen, then again you aren't doing it right, with a few exceptions nobody short of taunting has pulled threat off of me.
Lastly you talk about Enflamed Rejuvenation
wondering if it would help you. People need to stop thinking that "heal tanking" is viable (no offense to you personally). I guarantee you that in ANY situation where a tank is required to control any mob (because it would destroy any other player in 1-2 shots) the self healing a tank "could" do is insignificant past their own tank CD's which in most cases is a shield or 3, increased healing done/decreased damage done for xx sec, and a 5/10m cd half-full hp ability. Even an off-healer usually cannot help keep the tank alive once the true healer dies for more than a few seconds.
You cannot be the best Tank possible while trying to be a good DPS and/or self healing thingamabob. It's no different from any other Role. If a DPS spec'd into a bunch of tanking abilities so they "could" OT when needed then they would not be topping the DPS meters (unless OT was their job, then it's appropriate). If a Healer spec'd into a bunch of DPS talents (discounting Bard/Chloro since that IS what they do) then they probably wouldn't be capable of dealing with the tremendous damage output of "I'm going to kill you now" boss move.
With all that said, since it is a game and people will play it how they choose, do that. If you want to be a 'healtank' then be one, nobodies going to stop you, but you will not likely be tanking end game content as there will be better tanks out there that realize the futility of trying to do the same.
EDIT: I keep seeing this so I feel it's necessary to reiterate a point, Glory of the Chosen
in the Shaman tree for those of you taking it so you can "healtank" WILL NEVER PROC, EVER
! If that ability ever procs then you shouldn't be tanking since you do not have the required Toughness to handle that content. Edited, Apr 27th 2011 2:12am by delindsay90210
