Ok, so I'm digging up and old post...
Regens, it's all about the recharge of your click heal powers. I did half and half on Claymore. I did Doc's on my click heals, and Num's on everything else. With a few accolades and Dull Pain you will be at the HP cap or really close to it, so more HP bonuses from Num's are worthless. If you can get perma Dull Pain going, you are better off than having a little more regen. If you can cap out on those 5% recharge bonuses elsewhere then go all Num's, but otherwise I would use Doc's on the clickies to get more recharge in. And, you want all the recharge you can get, cause there are lots of ice, storms kins, and night widows running around that can murder your recharge. Doc's also give you -duration of fears, which is really good with all the people using that in PVP and integration has nor protection against it. And lastly Doc's give you small amounts of resistance to fire/cold/psi/toxic and every little bit of resistance you can get on a regen helps too. So yeah, focus on Recharge bonuses first, Regen second, and the few HP bonuses (if any) you need to cap out once you have perma dull pain and the +hp accolades.
