I've been playing IS a lot lately and I like having multiple choices for healing options. Dwarves in general seem to be one of the most fleshed out races in the entire game, and I really appreciate that after trying to play some less fortunate themes. As for Amp Healing, I kind of don't want to run it as long as it's a global effect. It doesn't help that there's plenty of counters to healing in general like the aforementioned Skull of Decay, Dark Healing, inhibited/disease, etc. Even the possibility of having to try to deal with a board full of Regen 3 Draksars gives me pause running it.
