Due to Real Life I can't commit to a regular raid schedule, so I've been working on MTing my way through pug raids. I'm cleared everything up to Auriya in Uldaman (failed due to dodgy heals and retarded DPS) and with better heals managed to make it through to Twin Valkyries in ToC10. I'm pretty happy with my warrior overall but at the same time, I can see so many times when it wouldn't have been a wipe if I'd had Ardent Defender. The way I see it:
Warrior:
-10% Damage Taken (Def. Stance)
+6% Stamina (Vitality)
+Shield Wall
+Last Stand
Paladin:
-12% Damage Taken(!) (Imp. Righteous Fury + Shield of the Templar + Sanc.)
-6% Spell Damage Taken
+11% Heals Taken (!)
+14% Stamina (!)
+ Ardent Defender (!) (~+10% effective health plus automatic antiwipe)
+ Divine Sacrifice/Guardian
+ Divine Protection
+ More Threat
+ 30sec 3-target taunt
Compared to Warrior, Paladin has:
-2% Damage Taken
+11% Heals
+8% Stamina
+10% Effective Health
+Get-out-of-slow-heals-free Card
That all makes me go "wow, why am I tanking on my warrior?". So before starting to invest some time in his gear (3rd 80, currently fresh-80 tank gear but decent ret gear so no problem getting heroics) I'm asking for your input. Is it worth the hassle of re-gearing? My warrior's tank set is OK but nothing out of the ordinary, ~32k health.
