nintenn The only real gap between AP and PEN is Enchanting really. Everyone has access to FP now if they play their cards right. As players level up they're offered free capsules, not to mention chances to get free capsules every day which you can also stack. Also I Capsules like you mentioned, Conquest and we have Events. Even Fumbi can give FP stats perm sometimes (or temporarily). Also the F skills are bought with PEN and have nothing to do with AP so I won't count that as P2W.
Enchanting is the only real P2W thing in this game. When you come across someone that has max defense stat and Lv 10 Def piercing legit along with other top tier enchants yeah it's intimidating. We can get "okay" level enchants without uploading AP, but we won't get those god tier enchants without spending AP on reset insurance and lucky jackpots, and enchant delete to get rid of the stuff we don't want.
