"Bear Druids are definitely one of them, since they value different stats from Cats and Rogues."

yup, but as daniel and the blue post state, this is going to be addressed. you may want to read the entire post before you reply :)

All prot paladin relevant talents and spells have been changed to scale with AP and SP, so they will be stacking strength for threat and wearing warrior/DK gear.

Warlocks also seem to be losing out on the itemization as the class is built so heavily around stamina. Cant really see blizz making priest and mage gear that heavy in Stam, wonder how they plan to balance that out as well? Locks are supposed to be able to withstand the unescapable melee beatings through having a lot of health. Also with less stamina on gear life tap starts to look less and less attractive as a means of mana regen.

The only real problem I see with Pallies using the same gear as warriors and Death Knights is that unlike those classes INT will still be somewhat relevant for sizing their mana pools.

I am not worried about Prot because of all the healing that they get in raids with stacking stamina will mean they have large health pools to heal back and as such will be getting plenty of mana back for tanking

Ret is a bit of a different story because they won't have as much stamina so less healing on them doesn't grant the benefit of healing for mana, but as I recall in ret there is a talent that returns mana after you judge a seal so depending on how the mechanics of that turn out mana could cease to be an issue for Ret Pallies as well.

Holy paladins will be the only plate class that has their own gear as it will certainly have to key spellpower as a raw stat on the gear. Mana stats like INT and SPI will also be needed on said gear making the Holy Pally a niche with little to no overlap and usefulness to any other class.

That being said I am really happy that I have chosen to quit holy and respec to ret when the expansion comes out.

To Djinn,

Currently prot pallies are getting reductions in mana cost of their tanking abilities from talents up to about 30% reduced cost and also prot pallies shouldn't have too much trouble keeping their mana up unless they completely outgear the place.

For ret pallies there's currently Judgement of the Wise which with 3/3 it will restore 60% of the damage caused by the judgement as mana to the 3 party/raid members that have the lowest mana which can help as well as alliance pallies getting their own version of seal of blood.

Lastly for holy pallies I don't know much yet for how they're going to be getting spell power from their gear and whatnot but as a side note holy pallies (as well as resto shammies) don't need spirit on their gear considering they get nothing out of it unless outside of the 5SR.
