@Xenth II: Try out JHI vs. DFK, then do the same with Heavy Billmen vs. DFK.

JHI and Heavy Billmen have nearly identical stats, but JHI use a different and unbugged animation to Heavy Billmen, so are unaffected by the 2-hander bug.

The difference between JHI and Heavy Billmen is the 2-Hander Bug talking.
