The heat managament was different, but I was able to keep players up (level 20) in a 4man quest on Balmora.
Indeed, yesterday was the first time people in the PUG's actually commented on my healing, saying how good it was, that didn't happen prior to 1.2!
(I re-rolled on a different server, had a 50 merc bg)
Had to do some different rotations, but I am not really upset on the changes at this point.
