what if SR did 20% more damage? 15% normally, 7.5% to 2× resists, 30% to salamence and friends, and 60% to moltres and friends. is that "too much" yet? just wondering. (if your instinct is to respond with "yeah but it doesnt" don't follow through with it!)
Well nothing about "30% damage to Stealth Rock each switch" or "60% to all 4x weak pokemon!" makes me scream "broken" any louder than I was before (which was not at all). If Stealth Rock OHKOed all flying types, I wouldn't care (ok I'd care, but I wouldn't call it broken) unless the metagame sucked, and by "sucked" I mean "has major competitive flaws when you're actually playing the game," not "I wish I could use flying types."
So there's nothing about the percentages themselves that bother me, it's what the metagame would actually be like. To sort of better illustrate a situation in which I'd say that Stealth Rock would actually be worthy of a ban, let's pretend Stealth Rock did three times as much damage as it does now. At this point you're obviously playing a game that entirely revolves around Stealth Rock. Games will be decided based on who manages to make a couple good moves in the beginning to get SR up for a quick sweep, and that's just way too simple for us to tolerate as pretty much the main objective of the game.
In the end, we're looking at Stealth Rock pretty much being a game mechanic. "If you play correctly, your opponent is now punished for any switch he makes" is pretty huge (or people wouldn't be calling it broken), and I think that it makes the move, to an extent, indispensable for some of the same reasons that people want it banned ("it's unique"). If we could get away with "only" banning a couple of pokemon, and could otherwise keep this mechanic in the game without allowing it to become the
main objective, I would rather do that than test Stealth Rock.
So to finally answer your question: with 120% power, the most I would do is call for an Azelf test, see what happens and go from there, if the effects on the metagame were actually really harmful (which I'm not so sure is the case in the first place). I'd trade Azelf to keep (a balanced) Stealth Rock in the game any day. But there's definitely a point at which we'd have to utterly mangle the game to be able to say "hey look... Stealth Rock's balanced!" and at that point I'd be fully supportive of a Stealth Rock test/ban.
