imo b-reverse chef has too much endlag and the angle has is too inconvenient truly propel us any notable distance in the metagame. In neutral it's only really good at harassing bad characters that we didn't need chef to beat anyways and good characters have no problem punishing it. In friendlies with other G&W mains we've tried to make use of it but we would rarely get anything out of that worth making a fuss over.
As far as edgeguarding goes, it's an option, but it's a very situational option. A lot of situations in which you could use it, you're probably better off using bair or runoff dair. Useful, but not useful enough to be a gamechanger imo.
curious, does the new shield stun in the newest patch benefit benefit G&W ?
p much what JKBUK said, most of our moves are too laggy and dont hit hard enough to really capitalize off of it, especially against characters with good, fast oos options. we have a couple new tricks, mainly uair>jab>sometimes grab, but that's about as far as it goes for helping us. Defensively it doesn't help since our oos shield options aren't great.
I think something worth visiting is up-b gimping. Do it enough and you can condition predictable air dodges out of your opponent
It's more or less already a p big part of our (really good) offstage game, not much more to explore about it.
