Simply:
Turn off PvP Kill count in prt_gld
OR
Enable Kill counts on all WoE maps.
Despite this WoE =/= PvP argument...what are you doing when a sinx tries to break your emp:
You just stand there and watch them because you're only there to hit/heal emp. /endsarcasm
It's all PvP, either count it on everything or don't count it at all.
