the solution is a self supporting one: if you do not like the fact that you, as an imperial, cannot get into anything other than huttball, or if you as an imperial crave a challenge of fair or even overmatched combat, then you can roll a republic character.
the incentives are that you will get into all the warzones more quickly and more often. you will have the challenge that you want pvp to be.
but instead, you demand that bioware give you something else as your reward. an addition reason to do something because the in-game reasons are simply just not enough for you to be bothered with switching factions.
i agree with the sentiment that the cause does not lie with bioware but with the players. More players want to be the bad guy. If the good/bad imbalance were just experienced in this game, your point would hold more validity. as this is not the case, your point loses credibility.
