This is a nom I've been wanting to do for a while, and I think in this meta it's finally time to nominate Rotom-Fan for a rise to B-. I've found Rotom-Fan to be very splashable lately as it functions as one of the few Durant counters (Nobody runs Rock Slide anymore), a Fighting check, a Flying check, and a status spreader all in one slot. It can provide your team momentum with Volt Switch, has some offensive capabilities in Thunderbolt and Air Slash, and Will-O-Wisp is an awesome move in general to wear down the opposing team and cripple physical attackers, especially ones Rotom-S can switch into, like Mega Steelix. It's lack of reliable recovery is also mitigated a bit by Pain Split, which can be pretty cool to wear down mons and also get a ton of HP back from mons like Alomomola. In a meta where Durant is at it's best and Fighting types are everywhere, Rotom-S thrives a lot by checking a lot of these threats, but the reason why I'm not nominating it for higher than B- is mainly because of it's weakness to Stealth Rock, which can severely reduce it's pivoting capabilities thanks to Pain Split not being that reliable. But overall, right now Rotom-Fan can thrive due to the number of things it can check, mainly Durant, Fighting types, and Flying types like Fletchinder, and a lot of teams can appreciate it's pivoting capabilities, and overall I think it's a great mon with some support needed to fully work.
