Cool - that should help a lot.
(Free back attacks make players much more careful about posturing.) #5 (i.e. "the combat system") also includes other things, though:
1. Natural roll of 20 should always hit
2. Natural roll of 1 should always miss
3. Monsters requiring +1/+2/etc. weapons to hit
4. Missile range attack modifiers (long/middle -2/short -5) - otherwise you can just kill everyone from far away
Etc...
But yeah, I am waiting for my windfall, too
