The potential dps of any class is moreso limited by their abilities (disciplines, spells, AA's) than their gear, if you are looking at raid geared toons in general. There really is no such thing as "tank gear" and "dps gear" in EQ beyond items that have stats useful to a certain class and ideally you would want all the melee dps things like ferocity and cleave on a tank anyways so I am not sure where you are going with this.
