Yeah, a rule that says you can't fight for 3 weeks, because you were in a fight, is an anti-combat rule. Just out of curiosity how many people that dislike healing surges played Wizards? Because really the old way was another screw the fighter rule. You stand in front and get hit, while I nuke, you need 3 weeks to heal, I'll be fine tomorrow (once I get my nuke back). Even if I do take damage, I'll be fine in a few days (fewer hit points, takes less healing). That's right, the guy who was trained at fighting, couldn't handle a fight.
This isn't at all productive.
I play martial characters about half the time, primary spellcasters maybe a quarter of the time, and others the final quarter.
Yet I want my fighter to sometimes get really hurt when he heroically defends an NPC or the frail wizard. If all it requires is a five minute breather to come back from it, I don't feel there is a real cost. And heroism is, to me, all about making sacrifices for a cause.
