More beastmen of all levels please. It helps remind you who your main rival in the region is.

Aside from that, I can't think of the last FF game that had a bear in it, so that'd be something interesting to see. Lions are awesome too. I want lions. I'm not biased at all!

I think overall, though, there should be more focus on beastmen/demons/elemental types and less on common animals. It helps you feel more heroic if you just spent 5 minutes struggling against an evil looking demon or undead type than if you almost got killed by an overleveled marmot. I know the old FFXI saying "no matter what level you are, there's a rabbit somewhere that can kick your ass" but it's not very heroic for 90% of your kills to be animals minding their own business.
