Awhile back I queued my merc up for HM Foundry - got a group with a Jug tank, sorc healer, and a sniper. We all loaded in, did convo, and headed to the airlock.
From that point it was like someone lit a firecracker in the butt-flap of the tank's armor - I've done some speedruns, but this was serious balls-to-the-wall moving. Healer almost wanted to bail and the sniper and I were doing all we could to get in attack range by the time he aggroed - even outran the healer more than a few times.
No one died, not even him
Thus far best tanking job I've seen and one of the most fun I've had on a run
