Its somewhat subjective, and I haven't played monk a lot recently, but the unarmed razorclaw shifter's hit box feels really small. Have to be sitting in the mobs lap to hit them.

The first two animation attacks in particular seem to have an extremely small hit box. I found a distance from the training dummies where attacks 1 and 2 in the chain never hit the dummy, and attacks 3 and 4 always hit. The distance was pretty darn close to the dummy.
