We've had similar discussions before in heRO, but we decided to only do non-trans and no extended classes like Aldebaran. The most problematic one is the lack of participation. We only have 100 players if we exclude the auto vending merchants at WoE time. Not everyone PvP/WoE, so let's assume that only half of the server population goes to war. We already have 4 castles, so that's... 12-13 people in each castle only on average?
We do have something sketched out in terms of an alternative WoE, but that is barely into the planning and far off before we can even make mention of it for public inputs and opinions =(
(So, the best cure to this problem so we can have a variety of WoE: vote for heRO so we can grow as a server. Tell all of your friends about it!
