Based on feedback from my first play test I am redoing all of the combat skills and I'm looking for feedback on the first one I've finished; Brawl.  I'm putting this in first thoughts because this version has not been play tested at all.  If however it belongs in Playtesting I apologize in advance.

The (slightly outdated) basic rules can be found here:

Most of all I'm wondering if the abilities seem varied and interesting or if it just feels like they are all slight variations on each other.  Because of how I am redoing the Counter/Follow-up system they are now need to be much closer to each other in terms of power/usefulness so I'm concerned I'll end up making them overly homogeneous.  Any other feedback is welcome as well!
