lol...stop changing the subject on me and then calling me naive. You said that removing swift swim removes an entire style of play because you naively thought swift swim offense is the only type of rain HO and I proved otherwise. No one said anything about whether it would be better than sun or not. And it's plenty worth it to use politoed for the bonuses rain provides which includes 100% accurate thunder and hurricane and -50% fire on top of making use of abilities like rain dish and hydration.
Just because you say something has been proven invalid doesn't make it so. That's what people who have no valid arguments say to try and end an argument as if it shows they're right.
And swift swim as an ability is broken. It's effectively an ability that raises speed by 2x. When you compare it to other abilities like download, guts, quick feet etc anything that alters a stat, it only changes it by 1.5x or 1 level never 2. Therefore, as an ability, swift swim is way better than most other abilities.
but as you pointed out, its mostly on pokemon with low atk/satk. It has not only a large number of counter, but a weakness to many different normal styles of play (such as paralysis) that can easily tank many hits from any swift swimmer and paralyze/poison/burn or just kill. Here: If you take an entire team of swift swimmers and drizzle, it is nowhere near broken and just as gimmicky as ran dance was in gen 5.
You are arguing that an ability that has easily been walled and stopped for generation 4 would now... not be walled and stopped when even more counters have come up with no new abusers? I do not know how you can think that it is broken. The problem, as i said, is the switching and stalling counters.
edit: wording was confusing, sorry.
