Just a thought...

I think it could be kinda cool to have some kind of skill or something for Centaurs where they buck and flail their hoovs at the enemy. Any thoughts on that?

This is a good idea. Centaurs need a bit of a boost to make them attractive enough for people to use them, despite their max stat deficiencies. This additional act, coupled with their KICK may offset the disadvantage of no AC, +dam, +hit, +str lost from no leg/footwear equip allowed that these Centaurs deal with.

The problem with a centaur related skill is that it's dependent on race and not dedication, and once I open up that bucket of worms every other race is going to want some special "racial" skill... which I'm not against, but not ready to do at this time

Valid point Blobbie. When there are ideas for all races, and when time permits, and when this sort of thing moves up on the priority list - that will be the day to consider it!
