So I don't imagine there are many people who aren't aware of this fact already but, if you do not know, there are 6 CPUs that are not in-line with the equivalent CPUs for other classes.
I'm speaking of course of the Long Distance and Close Combat CPUs.
Compartively speaking, every other equivalent (APU, PPU, HC, MC, Drone) provides +MainStat while lacking one +SkillStat. This does two things:
1: Impedes leveling progression for pistol and rifle users.
2: Hampers end-game setups for classes that need to eke out the most efficient +Dex that they can muster.
One of the biggest benefits of adding this back in will be the boost provided to PE's. It is commonly complained about that PE's are in need of some form of balancing to improve their viability.
