If you could choose any company to design a new map/class/item.

Who would it be? From people like marvel to even apple. Who and why?

Gravity to design an alchemist job. They did a really good job with them in RO, I would have hopes for them to do so in Maplestory.

Well if we are going for OP classes then I'll go with Riot games lol.

I'd go with Riot.

Square Enix, no doubt. specificaly akihiko yoshida or Amano.
that would be an awesome class, outfit, equips, etc.

Tetsuya Nomura of Square Enix to design equips. His designs have subtle meanings behind them rather than throwing things together.

I'd either go with Capcom and/or Atlus. Capcom for the use of the various sprite libraries to use as pets and/or gear. Rockman/Megaman gear and using any of the pet mecha from that series. I could also see them making a few Ghouls 'n' Ghosts sprites for warriors as well.Probably Atlus for access to the use of the entire Megami Tensei series amongst other properties they have as well. I wouldn't mind having Jack Frost as a little pet in the vein of the Jr. Reaper.

Valve. TF2 and DoTa. Nothing more to say.

Square Enix hands down.
I love the maps in Legend of Mana.

Valve or Capcom.
I mean, MEGAMAN.
Wait....what if...
OH pomegranate.
JACK IN! MAPLE MAN, EXECUTE!

I heard there's this company named Nexon. We should get them to make another warrior job!

Southperry.

Valve or Capcom.
I mean, MEGAMAN.
Wait....what if...
OH pomegranate.
JACK IN! MAPLE MAN, EXECUTE!

If Capcom got involved they would release new classes as expensive DLC. Then they would release a new version the is not compatible with the old DLC. Cacom might be the only company I have less respect for than Nexon.

The belts represent pain. Zippers........................................ the meaning of life.

Level-5. I don't think I've ever played a game from them that wasn't really good.

I want to say Valve, but I'm not sure if my characters I create will be epic enough for them.

Riot Games I guess ;3.

Valve, but only if IF is helping them design and balance it.
That'd probably result in a class i'd log back into maple to try, huh.

Google.

It would be batshit random and change every day in correlation to the Google Doodle. You could never get bored! <_< I don't know.

If Capcom got involved they would release new classes as expensive DLC.

Or release a full class and then lock away parts of it and make you pay to access it. Oh wait Nexon already done that with Dual Blades and Evans.

The best people to make a class in maplestory would be Inti Creates.

I'd definitely want Valve to be in charge of Maple if I had a choice.
