Will agree the br system is far more flexible and potent then the sc system ever was. Hell i managed to do a regiment of ruin(i think) with a friend who was out goofing around on bot. (Stone throw -> Maim) Poor Gertrude didn't see the 2k Maim i dished out coming, Hell even i was surprised by it.
Now if they keep the same basic framework and allow auto attack to continue working along with adding in actual animations for the successful regiments it would be darn near perfect. Ya know the thing that really makes br's brutal and i mean bording on exessive force and treding into possible war crime territory is that even with out triggering a successful regiment (which like i said earlier is pretty hard not to do) you still gain the benefit of the progressive damage buff for the skills further down the line.
