Had my butt handed to me five times in a row against some Greninja/Luigi player named DooM. Fitting name because I think it thoroughly crushed my spirits. I'm emotionally drained, like I don't even know if I want to play for the next few days.
The guy was moving at a breakneck pace, had perfect positioning on-ground, and after every stock he moved around doing what I assume are sort of hand-warmers, because it was faster than my reflexes ever will be. Dash shuffling, hopping off stage/back on, jumping/dropping, more shuffling... It looked like a Melee player's speed.
...Greninja is low on tier lists, isn't he.
