Maplestory "High Five" Private Showcase

i have always liked the idea of enhancing your previous skills as you went by, making even the initial ones good, so far i'm interested.

Yeah, I noticed that all classes seem to have Enhance Cores for their 1st, 2nd, and 3rd job skills, even ones that are objectively useless once you replace them. Will those cores make players' earlier skills viable as endgame damage options? If they will, then that definitely makes me want to get my Thunder Breaker to 5th job some day!
