AP give back

Just for clarification, do they mean you get all your AP back from ranking it (after learning) or it's only the 5 AP required to learn the skill? Several ppl have asked me this and some aren't ranking Beserk or Spider in anticipation for a possible upcoming all-AP-give-back event for them. I think it's almost definitely just the 5 AP for learning but we would appreciate some clarification. Thanks

Now, what kind of sense would that make? If the event gave all the ap back from F to 1, everyone would have r1 by now.

The page is petty clear about receiving a 5 ap pot when achieving rank F.

And why in the world would nexon host an all-AP-give-back-like event?
