I know we have like 4 aggro skills, but I don't think they stack 'Taunt'. Just basing off experience here.

I was at a Guardian group earlier, I had a 2x damage pot on, but my Taunt skills just wouldn't pull off an Operative (no damage pot) aggro. At times it would, but I believe that the Op probably just stopped using skills for awhile.

Taunt should guarantee the aggro, IMO. Anyone else's experience?
