that a risk of elite farming with random people. i suggest you to do elite farming with your friends, some thing like that often happen if we just do elite with random people. some warrior is new player, they dont know how to do in elite map or they not strong enough to tank, some of warrior level 20 use level 16 gear. and even a "pro" player can do some bad thing they provoke all minnions around jarl just too prove if they strong and ended with a mess when they dead.
