Little late, but oh well.
That.. third combo you showed starting at ~0:18, you ended with a (air)grab. I might just be imagining, and assuming that the class works like spearman, grabbing is real broken, are you able to add in another grab after the first one? I was thinking no, since the character falls toward the edge and isn't grabbable anymore, but I don't even know anymore.
Either way, nice video.
