The problem I have with Vette is that I Force Charge into a cluster of enemies, start doing some damage, and Vette, blazing away, grabs aggro, the enemies rush to her, and I have to (slowly) run back to her because Force Charge hasn't finished its cool-down yet. It's kind of like she's a ranged tank instead of ranged DPS. I don't think she as an overt Taunt ability, but it sure seems like it.
