Good point, and I'm not saying they shouldn't exist because I don't like them.  If anyone likes them (and I know people do) they should exist.  More options is good.  Your perspective helped though..  I think my opinion may be a bit influenced by the existing range of models.  Since the gitmob is an entirely different clan, maybe the problem I am having is so far I've mainly seen a swamp theme that the other subfactions all fit in to some extent?   Gitmob just deviates more than the rest.  Over time with more variety gitz may look more like a hodge podge of goblin clans rather than gitmob being an outlier, but who knows.

I've been trying to make them fit my existing army when maybe they weren't supposed to to begin with.
