I got done reading a book today and thought this might be kinda neat in AO..
Some of the professions that could use some love could maybe cast a temporary (1-hour?) flying vehicle that their character would be positioned on top of. This would be available at...oh, midlevel? 100 or so.
For example, an adventurer could cast some oversized bird to ride, an engineer could conjure a mechanical vessel. Nanotechnicians, some odd abstract flying boat or something. A martial artist...perhaps something spiritual, I dunno. A big grasshopper? ;P
When the nano ran out, the vehicle would simply deteriorate and send the character riding on it toppling to the ground.
Comments? Suggestions? Mild flames? :P
