Rain was clearly a bit much, and it needed a nerf in order to maintain competitiveness. Rain doesn't need 19 bans in what is essentially crippling the strategy. I think we dealt with rain well; it's no longer ridiculous, but it's still viable in OU. There's a distinction that a few people aren't making between dealing with each pokemon on an individual basis and dealing with a strategy collectively. No individual logic can be applied here, partially because rain is a strategy, not just 2 or 3 pokemon and partially because a complex ban must account for more than one aspect. When considering, say hypothetically, a Latios + Ttar ban you have to consider both pokemon, and the metagame on which they are suspect. You can't just consider Latios or just consider how Latios can revenge Ttar's "counters", it's much more of a collective judgement.
And I don't see any rain/ sun analogy. The types cannot be compared; chlorophyll users don't get STAB on fire moves; there is a higher degree of versatility to rain, both in strategies and pokemon available. Especially now that Blaziken is banned I don't see the necessity for any sun ban, and it's ridiculous to ban a strategy on principles because it's a bit like something else.
