You should be fine - we only have two characters so far and neither are urgists.  I'm guessing XSilentWingsX and 71342 [i]might[/i] be urgists based on their chosen roles, and I don't think we know about anyone else yet.  Even if we have multiple urgists I'm betting they'll be playing completely different roles - maybe your character has incredible finesse and can use her spells to move undetected amidst her enemies and wreak havoc behind the lines, and maybe another character has incredible strength and can send a gale ripping along the decks of an enemy ship.  Different charas, different skills... I say go for it if that's what you want ^^
