Oh yeah hahah, but he'd only want to do with after the drop kicks are charged up, not before because you have to release D, then press CD to get it to combo.
Speaking of which if you know that Raiden is going for CD counter -> drop kick, you can bait it out with late jump attacks, land, block and punish.
By the way, I'd like you guys to understand we're not defending Raiden's drop kicks. We're more information about what you can do about the dropkicks, because it seems to me people have a hard time understanding that it's impossible to get around. I'm sure everyone would like to see the nerf, including myself. Personally I'm just sick of all the crying about the move, rather than doing that, constructive discussion for figuring out how to fight against it is better. I'm pretty sure SNKP knows how much people hate the move with a lot the Japanese players using him now so bitching about it here isn't doing any good.
