It's just that more randomness is going to hurt the players in the long run, and I'd prefer an actual system if you want to do cool things--perhaps something like the Combat Challenges and Stuns from Iron Heroes (http://www.scribd.com/doc/230800066/Iron-Heroes-Challenges-and-Stunts), Raising the Stakes from E6 (http://www.dnd-wiki.org/wiki/E6_%283.5e_Sourcebook%29/Variant_Rules#Raising_the_Stakes), or various Combat Styles (http://www.scribd.com/doc/230800609/Pathfinder-Combat-Styles).<br/><br/>I'd personally be open to any one of those.
