The return of Dungeon Fighter Online (OPEN BETA PT. I STARTS MARCH 24TH!).

Because they are cheap, tired rehashes and I think they were made without much thought to balance.

Check a few vids.

So I guess they're overpowered? Dark Knight, I can see, it's just reanimated amalgamations of the Slayer's subclasses. Creator, I like that I could use a mouse for fighting, but I take it that just standing there, waving your mouse isn't all that romantic. Also, why the pineapple is the Dark Knight/Destroyer named after an Asura/Gunner subclass?

Creator is a character that uses WASD to move and uses the mouse for her skills. She's not very good and can be considered a "farming" character for low level dungeons, but they're pretty bad at anything endgame anyways.
Dark Knight has access to most of the Slayer subclass cubes and has the ability to cancel them into one another quickly, with the skills rising in power the later they are in the cancel sequence. They're notorious for doing broken amounts of damage with Stage 6 cancel ISD.

Creator kinda feels like she has no place within DFO, and Dark Knight is a rather lazy rehash of Slayer skills. They both don't have awakenings and can't do otherverse dungeons(Although Dark Knight is crazy strong despite having no chronicle gear). The biggest reason I don't want Dark Knight in DFO is because they're REAL dumb in PvP, especially depending on the incarnation we get. (They've been nerfed HEAVILY in pvp multiple times but they can still do insane amounts of damage past the combo damage cap).

And there's that, I see. Well, that's a disappointment.
