Maple Story has new characters what do you think about them?

Tweet

I have played maple story for almost two years and I really enjoyed their active community. I left the game before because I found a better MMORPG game to play but I decided to check my maple story account to see what's happening. I was surprised that there are other new characters such as the Cygnus knight and etc... Anyway, I havent' tried to make any character on those class yet and I want to ask players of maple story here about their opinion.
