I dont see why you should leave it out. It is still a good attack and the more attacks , the better, for claws. Especially if u get slowed, u have more attacks to cycle through while u wait for recharge. Claws attack are FAST (except eviscerate). Since claws is not a burst damage beast, the more attacks u have, the better. Swipe is good enough for an attack chain AND remember with follow-up on that attack is just getting better.
Now, because i can not check exactly which attack is this, I am talking about the attack with the symbol of one white dot and not the one with 3 white dots. :-)
