I kind of support the higher FP cost per skill rank if a skill's being used with Redgull Augment and critically hits.

Make the FP cost of the skill increase equal to your Lightning Impact critical damage % (or a flat amount, based on your GUI), and it will be gold in some situations. And make it only affect skills that can critically hit with Lightning, not actual magic, because magic already costs a hefty ton and only summarizes to three techniques anyway.

When people build for GUI/LUC/SKI, it leaves small room for WIL and other means to build up FP. And HMC got nerfed already so, all the better. The damage is absurd, but what if they are left with 0 FP after a single use? They'll be forced to resort to basic hits, in which won't be a problem.
