That's part of my problem. I don't entirely know. Doctored Wounds was my first pick because I was just kind of frankenslotting, getting the best enhancement bonuses for the lowest investment of slots, because, while I knew I didn't entirely have enough slots to go around at lower levels, I didn't know which powers I'd need. It's my first time playing regeneration and fiery melee. But as I've gotten to level 43 now, slots aren't quite the sticking point they once were.
I still haven't figured out an attack chain. By this time on most characters, I kind of have an idea of which attacks I use most often, but with fiery melee it just feels like button mashing.
