My current main is an Earth Scholar. The proposed rules will not affect how I play my character. My stone elf is okay with the healer role... just don't expect a Life spell if you aren't a "friend".
However, having participated in a prior playtest, I can see how melee classes would not enjoy the new version. We've nerfed static damage (kinda... weirdness with critical attacks and empower warrior, not included), while we've upped body and armor. So without take outs, static weapon swings take forever to take anyone down. Maybe that was intentional, but man... I would not want to be trying to land 12+ hits (not blocked) to kill a minion as a fighter. It could be argued that you could stat the monsters down, but then you end up with the weirdness of people burning 10 critical attacks/back attacks, messing up that statting. I know that when I NPCed during the playtest, swinging 5s to 10s against a PC felt largely ineffective vs a PC. Disarms/Shatters, followed immediately by Slays/Eviscerates were deadly, but static damage took forever to drop anyone, when fighters have 30+ Body (70+ in a couple cases) and easily have 40 armor in the new rules (not including that ritual that doubles armor). Even scholars with weapons were a pain to drop. Seriously, I don't see how the proposed rules are supposed to help staff with statting, which I believe was a part of the reason to make rules changes.
