The 2D change doesn't look like a nerf...at all. Now it is more of a combo tool(not saying that it wasn't before) than a combo starter, like it was changed to give Carl easier and better corner carry. Actually his changes seems like they were made to give him a better corner carry, looks like Carl midscreen is a bit weaker now.
But what am I saying I don't play Carl anyways so I could just have posted something wrong, sorry if I did. Also, it's missing the 6B change in the list, Akira.
