Heh, people are just now freaking out about this stuff? It didn't seem like that big a deal to the European scene back when SC2 was "big," but maybe I'm just forgetting a whole bunch. Whatever, maybe they'll fix some of it before rel-bahahaha who am I kidding. Gonna be tapping ankles for ~25% damage all day.
Edit: To be honest though, while I haven't seen the other stuff in action, Maxi's 3B+K,B doesn't seem like a huge deal to me. It's still unsafe and linear as hell, and I doubt it's magically going to make Maxi S-tier. Mitsu's 2KB is about the same speed, does around the same damage iirc AND it kills step. At his absolute best, Maxi will probably be a poor man's Mitsu, which isn't a bad place to be, but it's not worth hitting the panic button over.
