Just quickly, gotta remember that hit the gaps is used at the moment by crit bursters as it applies to torso (unaimed) shots and bursts too.
It's -50 to the armor's modifiers so if an armor is -10 to crit chance and -10 to crit roll naturally, this perk reduces that to -5 and -5.
Your idea for In Your Face I actually quite like buuuut... Again IYF is used by some 1 hex bursters too :|
I would say instead of the AP regen when holding a Close combat weapon, add this in your face idea and extend it based on CC skill, the idea being a CC fighter is much harder to hit as he closes in on you (something like -5% to hit them for each hex within 10 they are of you).
But still the problem remains.. Won't people just hold a CC weapon in their offhand and use it to close distance (or regain AP on the run) then switch back to their actual weapon?
