Just played my first game as Kassadin since the patch
His W is amazing
It actually does what it feels like it's supposed to do. Every time I tried to drop a full combo on someone, I was still doing some damage after I blew R/E/Q. In fact, I even out-dps's an MF for my 8th kill. It gives you that little extra umph to finish someone off before running away to let your team rescue you.
totally boss
