You also get 25 Arena Points per tower you destroy. Pretty nice way to farm some WF parts.

It's a nice edition event to the server, however you need to be extremely lucky to get a decent group. Otherwise people will just afk thinking others will do the job for them, plus even if they don't, half the players are clueless on what to do :D which is so simple and yet people still don't understand. It's such a good event but people lack the findimentals to understand what to do, so goodluck! Hope people are happy with this event, cuz I am.
