I see that they're revamping the explorers... yet again

What else have I missed? Been out since... the samurai class came out, forgot what they were called.

Just looking for info on (if any):
New classes or changes to classes
New major training spots
New changes to equipment stats (ex: potential)
Major changes to the game (ex: mts being gone)

Anyone got anything for me?

Maplestory has unfortunately become a pay to play, it's very hard to get along well without paying money. Potential has especially ruined the game, complicating items and the economy. Come back, ms is fun playing it with a few friends oldschool, but it gets hard later in the game without money.
