I played with Shredder today and it's so OP, I hope they nerf him before releasing.
It's like, he can flash easily with a double W, or he can double attack you AND flash to change the focus.
Also, that Ultimate is so freakin' awesome that my notebook can barely handle it.
Using Energy, the CD and Energy Cost getting smaller after every level on skill, it's awesome to flood skills and harass, specially with Q, and if you get the W fast, it'd be great, you'd be able to harass your enemy without being next to their tourrets. Oh, his ultimate has a 72sec CD, so flood it.
