Endurance Drain Issues

Hey all, Ive been building out a Psi/ tanker for the last few weeks and Ive been pretty happy with it. There's strong survivability in my build and Im comfortably tanking groups of +3-4 lvl enemies. Except if there is any form of endurance drain... I get obliterated if there's so much as a couple of electricity users, or a single Carnival of Shadows boss. Gods help me if I come up against a Malta sapper any time soon.

So my question is, what can I do about this one particular endurance drain weakness? Is there anything enhancement or power-wise that can help? The Psi armor has one minor resist to end drain but it seems to do very little and I don't think there's a way to boost it. Is there anything in incarnate I can look forward to down the road to cover it? Any suggestions are greatly appreciated.
