First off in the realm of BW2 OU rotom-H is objectively not a good defensive pokemon with or without SR. If it still had its ghost typing them it would be great but fire electric really doesn't have any brilliant resistances. Rotom-W is the premier defensive appliance for a reason. It checks the mammoth threat of boosted rain attacks and hits sand hard at the same time. Yes rotom-h can check sun... Why is SR stopping it? If it checks sun so well shouldn't 25% + lefties recovery be a sufficient trade off? It can check sun.. You just don't want to work to do it. You want everything to be automatic and archaic like we are playing single player pokes and that is not how competitive gaming works. Yes those metagames without SR are good but the number of pokemon have more than doubled. The amount of strong pokemon have simply increased out of control to the point where we can't ban everything. This is the basis of the problem with the pro ban side. We talk about this push and pull and having a counter for everything . Well gamefreak freaking gave us everything we needed to have to make this possible in the move SR.I don't think I missed any context here, but... a defensive 'mon weak to SR can't do its job as long as SR is on the field. Rotom-H, who could normally taken on most of what Sun can throw at it, can't do so when it's taking 25% every switch in. This is also the case for Zapdos, Togekiss, etc... Similarly, speedy revenge killing Pokémon like Weavile, Aerodactyl, and Scolipede. The Pokémon they want to counter can simply switch out and wait for SR to take its toll.
Also, you mentioned how SR helps defense. Well, yeah, its so good, it helps quite literally every playstyle. However, SR on the field hurts defensive play more than any other. "Oh, look, Darm's now at 75%. Now to hit it with... Oh, crap." SR helps plenty of Pokémon hit their 2HKO/1HKO benchmarks. Stall isn't aiming for those benchmarks, its hoping that the opponent will miss them. Simply from my experience with Stall in RU, SR hurts more than helps. Yeah, Moltres is at 50%. Now, it'll Roost because, since this is a stall team, I can't carry six pokemon able to either outspeed and kill it at 50, or kill it at 100.
What? So what you are saying is that the reason SR harms defense (stall teams) is that stall teams don't have any moves to hit offensive pokemon hard so defensive pokemon have to just sit there and look at a weakened pokemon? What..... You have never seen a good stall team before have you?
SR is not a pokemon. So treating it like it is is doesn't really help your argument. Besides it is really easy to get rid of SR. Not all teams have a ghost so if you can remove the rocks once then that is pretty much the end of rocks for the game. If you guess that he/she will come in with a ghost you can blast it for the 1-2hko. Again the team preview helps with this.SR is 'unstoppable', even if it isn't going on a rampage with the power it holds
No I don't but when my opponent has rocks up I now have the additional option of calculating wasting a pokemon for death fodder. Losing a pokemon on my opponents SR to get switch advantage has actually won me alot of games. As far as me playing differently when I don't have rocks the only difference is I wish I had them up to make certain threats more manageable. For instance I was playing against a thundurus-t without rocks up and my super effective attack took him to under 25% and didn't kill him. Then he proceeded to sweep the remaining 3 pokemon on my team easily because I didn't have rocks up. I don't really get the point of your example about the skarmory and the gyarados and tyranitar. I advise you to maybe play more and pick up some tips from other users about battling.How many times have you played without SR on your opponents field? You mentioned you once laddered to 1700 without it, so you must know (also, this isn't much of an achievement, I hope you realize). Don't you play differently when you don't have it up?
