Notice I said DPS races, rather than playing the class as a whole and this is something flyingtoaster touched on: A good retadin distinguishes himself by how much he uses all his other tools to improve the raid. I know I'm constantly using HoSalv, HoSac, DivSac, AoW FoLs (or even heals with a cast time on fights like Freya), HoF, HoP, SacShield, HoJ and Cleanse to make things happen. Usually the use of such utility can mean the difference between someone dying or not, which in tightly tuned encounters is the difference between a wipe and a potential kill.
I have to disagree. Ofc, we all use salvation, freedom, sacrifice and the rest when called for, so i don't think those tools can distinguish the good from average player, more likely good from terribad.
If the raid tasks are well executed, i don't think that the raid should depend on AoW heals and cleanse from the retri paladin for boss kills. The whole "support" theory was dismissed as long as Ahn Qiraj raiding, and there is no room for hybrid or support role in WoW raids.
The difference between average and good retri paladin players i'm looking for - If, say, i'm good player, i have above average reflexes, i pay attention all the time in raids, i know my calss/spec and read EJ daily, etc. i should be able to open a bigger gap between the average retri player (we talk about similar gear/template ofc) damage done and dps and mine, like the good warlocks, mages, rogues etc. are able to.
The problem is that currently, there isn't much room for mistakes and poor execution in our dps cycle (GC said we r facerollerz after all ).
