Honestly, the entire Medicine pool is simply sucking powers and slots from where they could be more useful.
If someone needs assistance, standing on top of them, trying to use Aid Other, while you're tanking a group is sub optimal.
They'll get up, get whacked once, and they're frenching floor again immediately.
Optimal slotting for Health is the Miracle Unique, the Numina Unique and the Panacea Unique. If you have left-over slots (ha ha), the Regenerative Tissue and Preventative Measures Uniques are Nice To Have too.
As Myshkin noted, the EndRedux in Rage, and lack of Recharge isn't ideal. If you don't have problems hitting things, just toss two 50+5 boosted Common IOs in there.
If you want to boost your chances to hit a bit more, toss in two Membrane Exposure Hami-Os. If the market's swimming in Membranes, buy enough to +3 them.
Were I rebuilding you, I'd go after something like this:
Also, you've GOTTA be careful with those Force Feedback procs.
If you leave one in a power and don't turn it off, you get a skewed view of your native Recharge.
