Power balance have been changing in the server. Two months ago one clan had the monopoly of heroes, now 3 clans have Heroes. At least another clan will enter the S80 league the next month or so, ready to pinch Baium with several chars (I should know, I'm one of them :) ). Castles have actually changed hands in the last 2 sieges. Fortresses are being taken. Baylor is being farmed. Hellbound is being leveled up (thx Vith).
Things will get interesting in the upcoming months :)
And I can tell you, even if you are a very, very, very casual l2 gamer (no more than 10 hours a week) you can get to lvl 75+ in a month. Then S80 in another month (if you box, you're alone and need to farm everything yourself).
Another interesting fact about AW is that we have clans from all over the timezones. We just collide on weekends, mainly for the sieges.
So come and join the server. You and your clan may become a factor in the server power struggle in a month or two, plus we'll have more fun pvping each other at epics :)
