Ya, the timing can be a real ***** though. I hate accidentally falling on my back and eating a smash attack from my opponent lol. Doing the same thing with Fair is much easier. Although, I'm not too familiar with the dash grab follow up, that's interesting, especially when combined with roll canceling.
I'm doing really well with Wario on For Glory too (I've never done as well online in any other FG), played about 200 matches with 85% wins. Wario is so perfect online because he's heavy as hell, the bike is a scrub killer, and no one ever sees the Waft coming.
I recently played a match between me and some ZSS player. My opponent got a massive lead on me early on, by the time I killed him for the first time I was already over 100%. Anyways, since ZSS can't kill for ****, I was able to survive until 166% when he was at around 40%. Thinking he was safe, the guy has ZSS attacking while getting up from the ledge, probably thinking "what's the worse that could happen? I'm only at 40%...", I block the attack and immediately Waft and the dude died. It was my most rotten win yet lol.
