Pls,you have a skill called gouge that can be extreamly usefull in arena,for the godsake use it.I saw lots and lots people play rogue and always rush like a dump,then got hamstring and died.Dont say elf got good skill or rant but its actually you who dont know how to use your skill.
Ohh and another thing,pls dont attack the tank first but the healer,the support class.You are a damager,I count on you to kill the healer and the support so pls kill them first.Thanks
