Windberrl's Arm Gun

It does low damage and it supposed to pull them towards the user which i'm guessing is you. I used this many times in different situations but it has never pulled or moved who I was hitting. I don't understand it, am I using it wrong?

Also, its always being my default weapon and I have to switch to my gun, anyway to put my gun back to the default so I start there are the beginning of fights?

you're not hitting, I think. Getting hit with that typically stuns the enemy when you drag them. Also, if you're deploying Winberrl first, use shift to change to the weapon you want prior to joining the fight.

Im certain i'm hitting them, the numbers are popping up, even tried it on an afk guy and he didn't move =]. Must be bugged?

I found out how to use the gun, earlier it the servers were lagging so bad it wasn't pulling. If you shoot 1 gun then it barely pulls them with the server lag and they can pretty much walk in a straight line but if you shoot them both at the same time it pulls them towards you pretty nicely.
