Substituting "tamers" for "flyers" would be good, they could have a choice of say a small dragon (because hey, that can get out of hand unless if your pet turns on you, it's now a sudden Boss >___> Awkward) or fish or something useful within reason. And then "riders" could have either a bike (I'd refer to Haseo in G.U but you haven't played it) or maybe some hoverboard. 

I do think the weaponry for the Mechanics should be more laser/plasma/sleek/hyper ish. Like with more updates than just guns. But we'll see what happens. As far as character creation goes, I have pictures/ideas for either a Mechanic or a Mythic. 

It'll be hard to choose but they'll probably have bits of both down the line so I guess it just depends on what we want a bit more focus in. Would you rather a Mechanic since you're more knowledgeable with tech?
