Yea it's all about server. I was 100% pub before 3.0 on harb, pvp was pretty balanced.
3.0 hit, I decided to level my imps. This is not an exaggeration, I played 45 wzs last week on 2 chars as an imp, won 2 out of the 45.
Pubs are just roflstomping wzs. They are running tons of premades and imps are pugging to the max right now. I rarely even see guilded people in the wzs and if I do, never from the same guild.
The constant loss rate is of course making it even worse at 60-80 comms per loss means we aren't gearing up. I was able to buy 4 pieces of gear (left side cheap stuff) from those games. My pubs never lose and get 120-160 comms per game. Even with bad gear I get carried pub side.
Edit: played 8 wzs tonight, won 0. Even the imp v imp game I finally got in, was of course us imp pugs vs a premade. :/ I'm sure it will change when geared but man it's frustrating trying to gear imps to compete in pvp right now. And bolster seems just plain broken. PVE gear does jack.
