Effect of gear on PvP

In one recent comment thread the discussion turned towards whether PvP would be more fun if everybody had the same gear. I think it would. Look at the following picture that I found on some Scandinavian guild site:The problem is obvious: the premade team shown in the picture above, in the very best epic gear, will win every battle, even against much more skilled opponents. And where is the fun in that? The people in the screenshot have a higher meta-level due to gear, so it is like a bunch of level 65s beating up level 60 opponents. Not a fair fight, not skill-based, and thus not fun.

I find it problematic if time spent in PvE to acquire raid loot leads to people winning PvP. It leads to people that are only interested in PvP, or not having the time or guild to raid, to be effectively excluded from winning in PvP.
