I found on some films that people are able to interrupt in the middle of animation and perform the combo. Example can be seen on these videos:
or in https://www.youtube.com/watch?v=aJROSP49_O8&t=0h04m43s
It's especially apparent with Heavy Naginata combo that is actually Whirlwind and then Spiral of death
but in opposition to the videos when I tried it my character always
had to complete Whirlwind animation and then start of Spiral of death
, not before. Same can be seen with Axe Spear's Spin slash on second video - he stops left slash in the middle of animation and starts combo.
I, personally never made it and am thinking how is that possible?
