thx alot hmmm. It could have the rodents as one faction because it's just greedy to try to create factions for every type of animal. Also I think it would be good to have some kind of fish people but I have no experience in makeing skins at all, and to get them walking on their fins would be hard too.

If you want bites for the animals the wardogs are your best bet.

One last thing do you think it's posible to creat a troop that are normal but when they attack the enemy they send them 10 feet up into the air like elephants? Which would solve the problem of makeing supper human heroes.
