It's how Nexon fucks you, first it tempts you with sweets, lures you to it's van, then before you know it, it bends you over AND FUCKS YOU.
Secondly they're only acknowledging SP /RESET/ that's not to say the 2nd job skills that only max at 20 now will still guarantee you can add to third job skills as normal e.g. i could SP reset Pai so he can add to HP Boost but i'll still be out of SP for 3rd job if i haven't recovered the lost 10 SP. ffs game WHY
