I think you've hit on the major difference between PvE and PvP in this game (maybe all MMOs, but especially here). PvE is, in some sense, a power fantasy. PvP cannot be a power fantasy, because then a person comes out on bottom of the power struggle.
But in PvP, someone comes out on bottom anyway, usually because they have less in the way of experience, skill, resources, or teammates, which are things that homogenization will not solve.
