I can just predict your rebuttal in an instant, Pocket. I imagine that you would like to say something around the lines of "Stealth Rock isn't he only restriction in teambuilding. Strong Pokemon like Keldeo and Terrakion require a teamslot to help check them."
I agree that a lot of people seem to think this way, but it's simply not an accurate analysis of how SR works.
People need to stop comparing stealth rock—and whether it's broken—to a Pokemon entirely, for a couple of reasons
1)
Spinning isn't countering. I think this is a problem both sides have failed to adequately address. When you switch in a counter, well, their shit is pickled. You get five options for any turn, a move or Switch. Countering is makin the only non-sacrificial option be Switch. I brought in my RainTenta on your MixApe. Now you're forced to switch, an opportunity which i can leverage to do a variety of useful things. SR doesn't work that way. I don't bring in my spinner on my opponent's SR and force a switch. I'm not reducing the options your SR has by bringing in my Spinner. Spinning may be a product of countering—since you need to bring your spinner in on something it counters—but it doesn't actually counter anything. Spinning is simply a move reversing another move. To claim it counters stealth rock is like saying softboiled counters hydro pump.
2)
You don't choose who faces SR - What would you describe as a team "Not weak to Cloyster?" I'd say if you had 2 or 3 or maybe even 4 or 5 team members that got entirely shit on by a smashed Cloyster, but your sixth slot was Slowbro with Psychic, that you were not weak to Cloyster. Or if you didn't have any solid cloyster switch-ins, but you had a scarf Starmie (outspeeds +2 cloyster), and he had a fairly difficult time setting up—well, I'd say you weren't weak to Cloyster.
Now what would you describe as a team not weak to Stealth Rock? Don't respond, it's been said many times in this thread. "you don't need to run a spinner. Just use
six pokemon who don't care about SR." I'd recommend that people use a solid check/counter for every offensive threat in the OU tier—for the especially good ones, two checks. But only for Stealth Rock is a team described as not being weak against it when NO INDIVIDUAL POKEMON is weak against it. That's because, unlike a Pokemon, SR is always on the field. You can't keep SR at bay with a solid counter, allowing you to bring in your SR-weak Pokemon because switching to SR will be futile while you still have a Tentacruel. SR is already there, hurting your Rock-weak Pokemon. It didn't need to switch in to do it! As such, unlike with Pokemon, who require perhaps a dedicated slot to beat, Stealth Rock affects ALL slots. That's why people call it "extremely centralizing;" good Pokemon are centralizing; you have to run a counter. However, even in Excadrill era, grounded steels didn't suck. They had uses countering other Pokemon and when Exca came in you switched to Gliscor. With SR, that's not true. You'd better be damned amazing if you want people to overlook that Rock weakness—if you can even survive losing 50% of your health to rocks, then you get to worry about the opponent's Pokemom you have to counter.
In case it wasn't obvious, I'm pro-suspect. I voted option 3 in the poll but the more I think about it the more I favor #1.
My main complaint with SR is its tendency towards an offensive game. Sure, say whatever the hell you want about Volcarona and Dragonite; if we have to ban them, so be it. At the end of the day, I'm convinced that Stealth Rock's net effect is wearing down switch-ins until they can be 2HKOed, and that removing that can only be good for the meta, increasing the counters list of every "borderline broken" ou threat (of which there are many)
Another complaint, though less major, i have is the move's centralization of the type chart. As I addressed above—there are seven Fightings in OU but that doesn't make Ferro suck. Only Stealth Rock has the power to completely remove the defensive potential of four entire types (unless paired with an SR-resistant secondary typing) (not that ice had much defensive potential anyway but)
