The problem with Besieged, is very few people care. Most of the high levels, just see it as a waste of time, and would rather sit in Whitegate while waiting for it to end. I don't know if they just don't REALIZE what we lose, if we lose, or what..but they just see no point in it. Then theres the fact that most of the people are busy exp'ing, fighting gods, doing dynamis, etc..and just can't help. Luckily for us, they tend to attack at times when people doing those things, are at a peak.
I love the idea of Besieged, it was just carried out way too poorly. They really should not be making it harder, or at least not now. Maybe they're adding another level to it, with another HNM or something, which isn't too bad, but my god..they need to fix the problems first.
