If you could add one thing to maple...

There also needs to be a much larger emphasis on partying. Instead of cutting EXP when partying with others, it should be raised, and therefore encouraged.

This was already done with Lionheart Castle, since the monsters there require a full party of strong members to be defeated in a decent amount of time. The EXP while in party is also increased there.

But yeah, they should increase the party EXP in all areas to incourage party training (which can be REALLY fun), or at least release more areas like that.
