Thanks everyone.
So that the same questions are not asked every time:
First of all,
I will make the Orcs a bit smaller, though they are already slightly smaller than men.
I took my reference from the movies and if you see them fight, they are actually not much smaller than man.
Anyway, as you wish...
actually orcs are almost upright in the movies. they could be slightly less upright, but that would require hundreds of new animations and for all weapon types. I assume that no one will ever do this for the little effect you would get.
Making the legs a tiny bit longer or shorter...; I have changed them a hundred times sand I won't make any more changes to the trolls, since they already used up too much time and the animation is ready.
Trolls won't be classified as cavalry since the AI would use them like cavalry (flanking). These trolls should be used as shock troops by the AI, so they will be infantry. Maybe Mordor can recruit some mounted numenorians from time to time.
No one said that they couldn't be a rare elite unit.
Animations for the trolls are all done, even two different variants.
