This is the % right now as i comment this. FYI I play on asmo side, and i agree that this prolonged lock is going to be bad. If someone is really determined to play elyos no matter what, they are probably going to play on another server which is a loss.
Asmos might have the lesser numbers right now, but there is an even bigger problem which is there is literally no leaders in the faction. The only siege that asmos go to is tia sieges. No one is willing to lead or organise for any other sieges. Even if you lock elyos any longer it is probably going to stay the same. Maybe increase the siege rewards so asmos will actually start trying?
