Interesting.
In my games seriously muchkining heal-bots like this will eventually run into a L+3 or L+4 encounter with intelligents (artilleries with a synergised soldier or three) that will focus-fire him the first time he pulls that in front of them. One round of good DM rolls and that heal-bot will be out.
Comes down to the fine line between good specialisation and metagaming/munchkining I guess.
Interesting indeed. I like your point.
I suppose I could be a little more mean on the focus fire.
Just hate to have to use the same tactic every time, and it stinks for that player to spend his turns just making death saves, only because wizards didn't think his powers through. He loves and cherishes his pure healer to death---always plays healers in every game.
My game has been running smoothly and fairly since I used the interpretation, "Mark of healing grants a save only to the direct target of a healing power." Before, they devastated my encounters, especially with the number of monster power save conditions in paragon.
Based on these results, I'd have to side that customer service is not ruling as they should.
