Anyway, it's true that the pink blobs are less used than in previous gens, but they're still plenty viable on stall teams (and honestly, that's really the only type of team they should ever have been used on). Tales and ttar are weather inducers--yes, you have to have a weather team to use them, but on the other hand, that makes them automatically some of the most useful pokes in OU and gives them a huge purpose totally outside of countering sect. Rachi was ever quoted as being a counter, but rachi is (very very commonly) found in rain, so rachi is a great gene counter for rain teams. First of all, volc can take any hit from +1 LO gene excepting thunder(bolt) even at half health (thanks to arcticblast for the calcs), but it's true that volc prefers RS support--if you're using volc though, RS is already mandatory. And it sooo does not need sun to beat sect--i could do calcs but pretty sure it OHKOs with like any fire move even in rain. Rotom-h is niche, as you said, but mostly it's just an example of an innovative sect counter. And SpD rotom-w easily takes a giga and twaves back, crippling sect. SpDtom is also a super useful set atm, as it and SpDrachi are torny's main counters.

The point is that most of these checks/counters are either weather inducers, or need weather to be as viable as they are, so the multiple claims that Genesect is needed to combat weather or that Genesect keeps the meta from becoming even more stagnant, is BS IMO.
