OK, this makes a lot of sense to me. While it still seems that the Imps have more roots and stuns, it does seem logical that the first side to gear up will win more often, starting an endless cycle. If the Imps have better gear on my server (Jedi Covenant), they win more, so they get dailies and weeklies done, get better gear, win more, on and on. As a Republic, I'm finding it VERY hard to even get dailies done. To win 3 times, I have to play upwards of 15 matches.
Contributing to this cycle are the frequent drops. Since winning is so important, I see a parade of people that log into the WZ, see we're losing, and leave again. The system really needs to change in order to break this cycle. Since winners get the best gear and then win more often, the system creates an endless imbalance. Changing daily and weekly quests to simply completing a certain number of WZ's or earning a certain amount of points, would help.
