Why do people dislike Nexon?

going on a blizzard tangent here, after playing SC, that kind of thing happens, balance isn't easy to get.

BUT THEN AGAIN, DB's, Mechanics, Arans when they came out, etc, are examples of bad balancing. and still several classes are, to better or worse.

Starcraft is a bit different. You arent specifically paying for the items (in fact, are there even items to buy in that game? I only play SC for the campaign). You only have to pay for the privledge to play.
Maple is different where they offer the privledge to play for free, but instead they charge for other things in the game.
