Just thought it would be good idea to give thieves some sort of boost to PVE. It could be totally PVE only and have no PVP benefit and so have no impact on current class vs class balance.

A level 35 paladin can kill a level 51 mob much much easier than a level 51 thief can generally.

It could either be tanking bonus or damage output or both.
It could either be mob only (though benefits vs charmies and cabal mobs) or only work with no pk bloody (truly PVE benefit only).

I don't think anyone would complain with thieves getting a boost to PVE.
