Treek. Although I really love M1, right now he's not that geared. (Just got him, hit Tat, only level 25). I have a problem with him not being able to hold aggro and gain as fast as Treek right now. Problem with Treek is that she is annoying as all hell. [un]Fortunately, she's practically a god. I'm CM specced, so I just target an enemy in a group, press Ctrl+1, wait a few seconds, then go ham on everything, healing as needed. She doesn't lose aggro. I can't do that with M1 yet, but the second I can, bye Treek. I know how ****** Yuun and Tanno are from my higher leveled Vanguard, so just biding my time...
