Well, the people that got ahead with the pre-perf phoenix drops aren't *THAT* ahead. Give it another week of people grinding at level 30 and they'll be basically caught up gear wise.
The larger and much more systemic issue is the rogue system being kinda awful at endgame. It worked great while leveling up, as taking items from people actually did kind of matter, but when everyone is 30 and 99.9% of the dropped loot in the DZ is worthless aside from crafting mats, why bother? The penalty for death at rank 5 rogue ismultiple darkzone levels, which takes hours to recover from, so why would any sane person ever do it?
