I suggest the following, to deal with the plausibility problem ( I find) of archers in melee who can 5' step away from the swordsman attacking them and get a full round's worth of shots into his face, with no AoO. I think archers in melee should be expected to resort to melee weapons, not fight with bows gun-fu style!
5' Step Ready Rule:
1. You can Ready a 5' step on your turn as a Free Action, provided you have not otherwise moved on your turn. So you could full attack and ready a 5' step.
2. If you have moved on your turn, you can still Ready a 5' step as a Move-Equivalent (not Standard) action. So you could 5' step, standard-attack, and Ready another 5' step.
Thoughts?
