Some pay attention, some wish to see something that isnt there.
Aimations are per form, since a thing of a certainshape moves in a particualr way.
Scaling the critters as you want them to scale requires a change in ai as well, if tve creature is a spell caster. Melees might scale better, but even then you would either have to rescript to add abilities, or have them be extremely generic. Which seems to be what you want them to be.
So my conclusion could be that yiu want the ai of mobs to be downgraded. Which i dont thini you want, but which would be likely to hapen.
