Believer, going on a journey...
The second you decided Swift Swim, an ability that does absolutely nothing without a Rain boost, was more broken than the Rain that boosts it and the combination of other factors that contribute to making Rain teams so overpowering and dominant to begin with.And since when did we pick and choose what to ban?
Did you ignore 90% of Rain teams running Nattorei with his reduced Fire weakness? How about Toxicroak getting free health and taking down your Rain counters? Voltolos getting Thunder? Tornelos getting Hurricane? Hell, have you even played this round? Rain teams have ridiculously high chances of overpowering non-Rain teams. These Pokemon all operate in tandem to abuse a field condition that makes them all way better than they should be. Together.
Once again, you're employing a separatist mindset and trying to single out what should be broken about permanent Rain when it's really everything. Drizzle makes entire teams of these monsters viable. Everything you'll commonly see on a Rain team abuses the permanent Rain effect. Even lesser factors like 100% Thunder, 100% Hurricane, or a reduced Fire weakness all culminate into making supremely difficult teams to face. That's why the weather game is as strong as it is now; you're most likely not going to win unless you can turn off the Rain.
We can make a lot of things "special cases" until those cases aren't quite so special anymore. If you can't properly explain why we shouldn't extend this line of thinking to banning certain movesets or other parts of Pokemon just to balance them, then it's going to happen somewhere in the future. The only question is when.It's an entire playstyle and as Aldaron said it's a special case due to it affecting so many things.
