In their last battle, the Ylvainans were severely lacking compared to a proper unit of 2nd-class pilots. Wouldn't it be great if one these Artillery Mech specialists chose to join the Clan? It needs one to teach the Ylvainans all the ins and outs of their bunker mechs. Ideally, they'd be a formidable force even without Ylvaine's intervention, and wouldn't need to drag him to their rescue every fight.
