My ret paladin is full 10-man epic and I can do 3k dps with food buff and elixir (depends on raid setup). I doubt you can do 4k steady dps on bosses that doesnt give critt buffs etc (Loatheb for example). Also on most bosses like Sapphiron, Grobbulus etc you have to run and stop dpsing (avoiding blizzards etc), so how do you still keep that up? You just stand still dpsing without moving or?...Post a picture of that dps or it didnt happen... (Oh, and what rotation do you use to get the dps you say you have?...)
