Map ideas (and lack of them)

[VoRteX]

Hey everyone,
i have a small team of people working on an rpg map, we've been at it for about 2 weeks, we had an initial plan but the plans kinda turned to dust ._.
the maps terraining and spells is almost complete although our main idea is gone,
can anyone help us for ideas? (These are big ideas, unique ones that set our rpg apart from the rest)
We're also looking for unique class ideas, if you have some random as idea that's never seen the light of day, let me know and maybe it will!
e.g having about 10 classes and each class has a spell to transform into a different animal or something (just an example) xD

Thanks

PS: Yes, i know you guys must be sick of hearing about rpgs ^^
PPS: I can get some screens of some terrain if necessary.
