First of all, there is no real tank at that level, neither is there any real healing. No one has the ability to tank at all until later.
All anyone should have to do is kill the normal trash, focus the elites, and stay out of the circles on the floor in BT/Esseles.
To be honest, any tank that's in Hammer Station should already have their taunts. At the BT level, no, but it's a 2 person FP. Hammer Station? Definitely need 4 and your tank should definitely already have taunts. If not, your tank probably isn't high enough level to handle that place anyway.
