It really depends, I'm pretty sure Cresselia is 3HKOd without Moonlight by any special sweeper with Surf. Well anyways, on one occasion, I have 2HKOd Chansey with Surf and Hydro Pump the following turn with Stealth Rock down. The fact that the best special wall in the tier falls to someone like Gorybyss is insane.
Rain Dance is pretty much an easy team to use, and most players play it with autopilot meaning they know which move to use everytime. Surf, Waterfall, Aqua Jet, Hydro Pump. Resisted or non-resisted its going to hurt. I've beaten some prolific UU battlers with rain dance alone with minimal thinking. I'm not trying to brag, but I seriously think Rain Dance is broken. I will post my team here and i encourage people to try it out on the ladder and tell me how easy you guys win it.
Ambipom / Uxie / gorbyss / SD kabutops / SD Ludicolo / SD Qwilfish
Ambipom has Taunt / Rain Dance / U-turn / fake out (252 HP / 4 Def / 252 spe)
uxie has U-turn / rain dance / psychic / Stealth Rock (evs to outpace jolly toxicroak)
the rest are basic 252/252. try it out.
Just a basic concept with this: overwhelm special walls with sd sweepers, making a clear path for gorbyss to sweep.
You have a fair argument against Rain Dance, but as you and others have said, it is a much trickier situation than anything else as to what exactly should be placed as suspect. If anything (hypothetical: I'm not saying that Rain actually is broken right now), I would be in favor of Damp Rock, just to keep Rain itself and all the key players a viable option but hopefully manageable enough to not be broken.
I'm just wondering about your team though: what is your check/plan for Shedinja? Uxie just doesn't cut it the way Registeel does, particularly without Toxic, and Stealth Rock doesn't help because Sheddy can just switch in on the same turn with impunity and SD up. Out of your four sweepers, only Kabutops commonly carries a move that can hit it, and has to be sacrificed to break the Sash.
I'm only saying because I have recently been using a Shedinja team for a bit of fun, as I have grown a bit tired of my old Cresselia team that gave me a 90% win rate.
