Ah, but no special characters get to use Accumulate, which makes leveling them much more of a pain in the ass. So if I don't get something good in trade off for loosing the squire job class then I consider them worse than generics.

The main problem is that the best classes to pair him with are stuff like Monk / Geomancer. However neither of those are all that great on their own right. Monks suffer from their lack of ability to equip equipment, and while Geomancers aren't a bad class they are also very difficult to tweak out and make good. Sure you can make him to suck, but it just seems like a lot of extra work and run around to get something not appreciably better than a generic.
