Can't do finishers

[(PSN)meehnohim]

I noticed bout a month or so ago I hadn't seen a finisher in a while but when they released mod for bronco that caused finishers I was excited until I realized the reason I hadn't seen 1 (finisher) in so long was because I cud no longer do them. I started with banshee and her 3 with augment and no finisher (animation) or I believe damage besides it would be hard to no wht damage was considering I couldn't do 1 to test. I also tried excalibur and his 3 with augment,valkyr 3 and again with the Bronco and new augment. I tried ash and to my surprise his 3 worked so I I thought problem solved I went and tried the others and same results. pls help d.e. I need my finishers!!!!!!!!!
