Since this is the only suggestion I've seen regarding new classes, I'm just going to babble my mind.
First off, Dragon Kin. Their classes are unbearable for me. I can't stand the idea of having twin characters, and the summoners/overlords are a little tacky and slow. I'm sorry if I'm offending someone, but that is just my opinion. I'd love another class for them. I think I've said it on forums before, but they could certainly pass as reapers or death keepers. Scythe as main weapon? Awwwwwww yea. I'd dig that.
Other class ideas (for either humans or dragonkin) I thought of...
- A katana or slim-blade class. Something not too similar to anime/Asian tradition, and not too similar to thieves. I like swords, but the over-sized swords on the warriors aren't my cup of tea.
- A class that specializes in boomerangs would be pretty new and interesting...
- I've seen the pirate idea floating around. Instead of a straight pirate (which would be too similar to a thief), perhaps a class that uses a curved blade (or two; doubles)? There was a special word for them, but I forgot. They're curved, and used in a lot of Arabic/Muslim-themed shows and video games. Heck, the class itself could be desert themed.
Yeah, idunno. Getting lazy here. But, you guys catch my drift? Yeah.
