I think a big problem is that siege can damage siege. this is how all siege wars begin, you cant ram or short range cata so you back off. guess what, they have a balli and maybe even a treb. so you build bubbles... etc. ad infinitum. possibly even revert ac nerfs.
get rid of the stupid contested state for way points. seriously, why should one troll be able to prevent an entire server from way pointing? its lame. no one enjoys this.
