I would pretty comfortably say that right now Captain Cold is probably the worst character in the game even though his damage output is insanely good. Honestly I don't even consider him part of the game at this point lol. The wall nerf was hilarious. Basically was their way of saying just don't play him.
I don't see how you guys aren't utilizing df3 as combo enders to mix up your bnbs and counters as CC.. I use df3 at least 10 times before end of the match and it's usually what keeps me from losing the life lead most of the time
