Thanks guys. We're going to allow them, since the models come with them. Thats usually been the rule I've used (that if there are models that come with it, that it can be used by that type, for example: Orcs with clubs)
Another question about Ungors that I had never really considered (since so rarely does anyone play as beastmen) but my buddy brought up:
Are they over costed at 25gc each?
In the "no" column: movement 5 is powerful, and is definitely worth some extra money. They have 1 more leadership than the 5gc cheaper Verminkin, which follows pretty closely with the accurate-ish guide of +5gc per extra stat.
In the "yes" column: they are leadership 6, as opposed to a merc warriors 7, initiative 3 as opposed to the Verminkin, can't become heroes. and have a very, very limited equipment list that they can never expand.
The argument in favor of lowering the cost certainly seems stronger to me. It really feels like they're more a 20gc choice, at most.
