don't spend money on maplestory lol
legit, you'll be spending thousands of dollars on something that ain't even tangible, don't make that mistake

It being intangible has nothing to do with it.
If you spend thousands of dollars on a trip abroad, and then come home with not much more than $10 worth of memorabilia and some photographs, was it a mistake?
It's perfectly fine to spend money on entertainment, on having fun that leaves you with nothing tangible. (If you don't need that money for necessities, obviously).
But, as I said, above, if you only want to spend money on the class that will give you the biggest numbers, MapleStory classes are not nearly stable enough to make that decision.
