NL's require a lot of funding do hit good damage. Not too sure about nerfs and buffs. Their showdown skill at 4th job is their mob attack and you get a 40% bonus exp from monsters killed, while using it. But generally NLs require tons of funding to hit good damage.

If you're planning on getting far, they're all pretty much gonna be around being just as expensive. All class can pretty much hold their own. Classes will always get nerfed/rebalanced at one point or another anyways. So if you enjoy something, play it.
If you can't choose between classes, pick the one you think you will enjoy the most. If you didn't like it as much as you thought you did, choose the next one. Rinse and repeat.
Nope. Nexon took donations to pay for the server to be kept up...they locked in 33 more months, but they're not making any changes or alterations whatsoever...just leaving it as it was in 2011. They got their eyes on Maplestory 2.
Nexon has been too focused on MS 2 which they haven't been focusing much on Maplestory it self. Apparently there's still glitch(Chats) etc, botter everywhere and even hackers and they won't even do anything about them. Some world merged with other worlds which kept the population but still the game is a little boring.
