Don't know how much longer I can do this

Leeching is legit. The only kind of leeching I frown on is the kind where lazy person A pays or is friends with person B, and hangs on a rope for 4 hours getting EXP. Lazy Person A proceeds to brag to all his friends about it, and suddenly half of MapleStory is too lazy to train.

I don't think you should be leeching, though - you should get to enjoy your class as much as possible, and not shortcut up to level X.
