^I know, it's a cool glitch.
HQQR, you know he does his moves just as fast as before?
The stinger, kick 13, pin-up all goes at the same speed, the combos too.
All he does is walk a little slower, as long as your in fighting range of your enemies you can still wreak havoc at the same speed with the Dreadnought.
One more thing, it is not rendered useless because you say so. It is in the game for a reason, it's the same with the lucifer. It is for those who like that style.
"I don't like moving slow so it is a useless move".
It's like saying: "I don't like playing Cloud in Dissidia since he is so slow, so he is useless".
