During Guild War between LaughinCoffin and GodEatGod, Jock3r , LaughinCoffin's guild master , used side buffs from players (probably multi-clients) , who wasn't in his guild and didnt wear PVP capes at least. As u can see on video (link below), it was party buffs from both of that players - Optimizer and chancedapink, and that buffs can be used only in party, so, Jock3r was in party with that players . To avoid any talking like "Guild War is bugged", etc, it was happened when Guild War has just begun. I don't know who should take punishments but one thing is sure, there is breaking of rule for outside buffs!
