Trying to heal your allies up in combat is also usually a bad idea. Unless you can heal more damage than the enemies can deal every round, you should focus all your energy on disabling enemies to keep them from dealing any more damage. And divine spellcasters have lots of spells that can take out enemies very effectivly.I've played every edition from BECM to Pathfinder, and I've never noticed any of these problems with the healing mechanic. It wasn't until I started reading the posts in the "New Horizons" forum, that I had even heard the term "heal bot." (shrug)
As far as healing surges go, I honestly hope that they add them...but make them optional, since a lot of people don't seem to care for them.
In combat healing is best be limited to patch severely injured allies up, so you don't have to deal with ressurection. But the most effective way to use healing is to give allies a chance to disengage from the most dangerous enemies. If at the end of the fight everyone is at more than -10 hp, everything is alright. Then you have time to heal. But a simple hold person spell should prevent much more damage than cure moderate wounds could ever heal.
Compared to 3rd Edition, I don't see any need to change healing in any way. Healing in combat already is a bad idea and divine spellcasters can help the group survive a lot better by using combat spells or even just attacking with weapons.
