Tankiness will increase, imo, if you change 1 of the EPTS to EPTA, then 2 purple damage control engineers to get their cooldowns to the point they're almost always up. Then the other damage control engineer that gives Aux2Sif a chance at a HoT, and the Maintenance Engineer that gives a healing bonus on EPTA.

That'd be full on tankiness I think, something in between that and a more offensive loadout might be where you land.
