The Impervium Armor: +Psi resist is pretty much a wasted slot, since you're already over the psi resist cap, and psi enemies will already have a hard enough time hitting you. I'd put that extra slot into health, and put the Panacea proc in, since it yields approximately 0.4 end/sec on average. I'd also say try to work the Preventative Medicine: Absorb Proc into health, as well, if you can. But the rest looks solid. That global recharge speed is really impressive.
Only real negative I see is that S/L resist is very low, so you may be prone to one-shots, where your scaling resists won't even kick in. You might consider just completing the LOTG 5-set bonuses for the large S/L resist set, but that's personal preference. If you gotta go fast, you gotta go fast. You are over the set limit on 7.5% run speed bonuses, so you should probably drop one of the Gift of the Ancients, at the very least.
