Last night i decided to play my PLD in a pug and then my DRK in a pug. Very stark difference in tanking methods, BUT the same effect. Only difference I noticed mostly is that PLD played with to many options. When to use clemency or not, divine veil or wait we have scholar shield, ugh!
Openers: Fight or Flight, Rampart
My main rotation: Shield Lob, Flash, Flash, CoS, 123 RoH combo, Flash, Flash, sheltron, Goring Blade combo, Flash; Generally sprinkle Bulwark and Sentinel in there

After main rotation into advanced rotation:Royal combo, sheltron, Goring combo, Flash, CoS, Sheltron, Royal combo, Divine Veil, Clemancy; Generally sprinkle Rampart, FoF, Convalescence, Awareness.

NOW THE PROBELM. The AOE in this rotation is just that, ALL I have is flash and CoS. Thats it! For me I hate trash pulls in raids, pugs. People generally don't care about enmity. Never had this problem with my DRK.
