I had one in a group today who had all the emp heal powers (and only the heal powers, fortitude apparently was too much for them), all of the heal/buff powers from the medicine pool, and for reasons passing understanding had also taken pacify, provoke and unrelenting.
And it's like, I get it man, you want the healer role, or you're roleplaying or whatever... but you're nigh useless to a team. You're not helping us fight things faster and if we pull too much, a couple emp heals aren't saving us.
If you wanna be a healer just play nature; at least then you can spend most of your time healing (however effectively)
