KMS max stats cap increse and stats reset

Ughh, I have the extra AP from whatever event that occurred in GMS so now I'm at Lv. 197 and I already have 14 unspent AP.

What should I do with these 14 AP?

Put them in your secondary stat (DEX if you're a Paladin).
Gives you some damage now (4 DEX = 1 STR) and will be covered by the AP reset Nexon gives out when the stat cap increases, so you can easily move them to STR then.
