Off topic, but as a Shaman main and hardcore raider, I ended up on a model M keyboard and even then, I still polished my 8 key (cannibalise) smooth over all those years
Everquest's style of combat had it's place, but that was in a time where we were on average much younger and could merrily afford to waste entire days on a raid or camp. A modern day raid is done and dusted in the time many EQ raids took to simply prep and setup.
Back on topic:
If you can count dual purpose abilities as healing, it can be done in a way that's enjoyable. It just requires inventive approaches. SWTOR did this well, Warhammer did it to perfection.
Abilities like current Lilies, Earthy Star and Macrocosmos show that they understand the theory, but haven't got to grips with it yet for whatever reason.
