stealth rock is so ridiculously overpowered that it is required on literally every team. it gets more usage than gsc snorlax for christs sake. it makes already insanely strong pokemon even harder to deal with. i could take it or leave it but id prefer a ban
You can't really compare a move to a single pokemon, SR gets really nice distribution and there's no reason not to use a move that gets chip damage on everything that switches in. Snorlax is meanwhile a single pokemon that despite its centralising aspects has remained fair to use in the tier, meaning that it's not broken (maybe it is, I don't play much GSC), or at least that people can tolerate it. SR is nowhere near as centralising as Lax, it's a single moveslot that can help support a sweeper or wear down a dangerous threat.
Okay, the absence of SR makes Loom and Nape a lot easier to deal with now that their checks don't have to lose a quarter of their health just for switching in only to watch them dance out for free. Great! The problem is that, as said earlier, it makes all of Zap+Gyara+Nite borderline impossible to deal with as now they are in the position of come in for free, put a huge dent in check, and dance out to something that handles it. Even with the Smogon metagame (SR legal) in use, user badabing, who's pretty highly regarded when it comes to DPP, said of Gyarados that 'I can't think of anything else that has as much of a chance to put a hole in or outright win any game' - do we really want to be making this monster more powerful? What about Zapdos, who comfortably U-Turns (or BPs) out of all its checks into Breloom who proceeds to abuse them? (I personally think Loom wouldn't be oh so troubled by SR gone as it can still get free entry from a newly empowered Zap and Sleep whatever comes in next, before setting up all over it). I don't think so. SR makes Nape and Loom really hard to deal with (ironically the loss of this chip damage on Nape which can be crucial if you're trying to stall it out and Loom's partners becoming overpowered af would mean that despite being individually less gamebreaking both fighters would still be just as threatening overall), but equally it keeps a lot of tough things (as well as mindless U-Turn spam) in check and I really don't think it should be cast aside.
In regards to the other proposal on the table (#FreeLatias), blatant no (as for the other Dragon, I can think of no better way to break the tier that banning SR and freeing Mence). I feel like the problem with Latias is that it would undisputedly be the top dog (top notch coverage, killer speed tier and solid offensive stats make it a threat, while simultaneously it hard checks Fighters / Grasses / Zapdos / Specially Offensive Waters and more, and of course it gives everyone another reason to run Heatran / Tyranitar / Jirachi, as if they needed one). I think we're all ignoring the possibility that Latias dropping (similarly to banning SR) could replace all our current problems with even worse ones, and I think that our current problems are fine (Loom is borderline manageable, Nape isn't but that's why we ban it, as well as Iron Head on Jirachi to keep it from breaking games, everything else is balanced atm). I feel like we should just get rid of what we know is broken rather than trying to dramatically shake up the tier because we want to see a certain mon (that was banned 6 years ago) back. Just my two cents worth.
Tldr: Keep SR, it checks two things for each thing it makes slightly harder to deal with.
When people offer you the chance to use a Latias, just say no.
Ban Infernape and IHead Jirachi.
