Vanguard Monks

i cant shake aggro from group by nerve strike splitting, because pallie aura is hittin me like a buff, not much trouble on regular mob's, but in pinches when tryin to split out nameds its a bish. is this intended or another bug? because i group daily with pallies, a few in my guild, one my RL bro whom i play with. plz tell me its a bug planned on being fixed, because they cant turn off their aura's.
