People are exaggerating way too hard on the shield stun changes in these videos.
Do you see how tremendous some of those gaps are? Some of them strings could have been done quicker with smaller gaps but still...
Hence the disclaimer: "These can be escaped with a quick shield drop, but if you're quick enough you can make them stay."
They're essentially "optimal" setups for shield breaks. Assuming a person does not know about them or doesn't react in time, they're getting a shield broken. There are still people who just stand there after something happens with ton of time for punishment not just from their opponent, but them too. It's like two deer caught in headlights. The time when Trela broke that Jigglypuff players like 9 times? That Jigglypuff probably had no idea how Collarbone Breaker worked or how to combat it. There is no exaggeration, but the two showing what Ryu can do to a shield in 1.1.1. The Luigi still has combos from D-throw video posted yesterday just proves one, Luigi can't true combo as insane anymore out of D-throw and two, Luigi's still got game. The idea that one change like that can automatically destroy a character is ridiculous. That move has to be beyond broken to affect a character severely if nerfed and even then, it has to be nerfed severely in some way. Case in point: Brawl Falco's Blaster vs. Smash 4 Falco's Blaster. Off the top of my head of beyond broken moves in Smash 4... Nope, ain't got one. Diddy's Uair was broken, but it was nowhere near the kind of **** in Melee and Brawl.
I guess the main issue would be semantics. Combos for many have to be "true" or inescapable or difficult to escape. For characters who can combo, but not true, they're usually regarded as trash and not combo characters. The irony when outside of Luigi, no character can true combo all the time. Hell, even Luigi had to 50/50 from time to time between killing with a Cyclone or a Bair. People end up calling those "strings" or even not combos and considered nothing meritable about the character. Also ironic when people hyped up patch 1.1.0 DK when he only has like 2-hit combos. This, compounded by an obsession with D-throw combos meaning any throws that setup or combo that isn't D-throw is somehow magically irrelevant. Remember Greninja's U-throw combo being regarded as nothing because he didn't have a D-throw combo? It's frankly very stupid. And now Greninja has somewhat of a D-throw combo, but people still don't give a damn about the tongue-scarfed frog.
