Hi, I'd like to nominate:
to move up from C- rank up to either C or C+. Right now its in the same rank as pokemon I personally consider pretty garbage in the metagame, such as Pangoro and Froslass. I definitely think it merits a raise to C, because I think right now its just as viable as other pokemon that reside in C which include Thundurus-t, Mega Blastoise, and Mega Ampharos.
Rotom-h is a cool pokemon right now and has a bunch of distinct niches it has over its Rotom-w couterpart. For one, the electric resist really comes in handy, seeing as how its super easy to pressure Rotom-w by using strong special attackers such as thundurus, raikou, mega manectric... Rotom-h has the ability to tank their hits and retaliate back with a burn or overheat and can heal back the damage from painsplit.
Another cool thing about Rotom-h is its grass resistance, meaning the stuff that normally beat Rotom-h (aka Celebi, Serperior, etc) lose to Rotom-h. Rotom-h is actually a pretty nice Serperior check since it resists leaf storm, resists hp fire, is immune to hp ground, and cant be paralyzed to glare, meanwhile offensive Serperior is KOed by an overheat even with 0 spatk investment. Rotom-h also has the added bonus of pressuring Mega Scizor and Ferrothorn if they're like paralyzed and cant be burned by will o wisp or something.
Rotom-h's fire typing is extremely valuable as of right now given the current soaring popularity of Spdef Talonflame, which can actually outstall Rotom-w if it burns it on the switch, because then it can roost stall so volt switch wont do crap, and its not like hydro pump is doing much damage after roost + leftovers, and you have to take into account it only has 8 PP plus it can miss. With Rotom-h, you dont have to worry about being outstalled by burn damage, because Rotom-h is immune to burn. Then you can spam discharge on it and paralyze it and heal damage back with pain split.
Did I mention it also completely cockblocks both physical and special offensive altaria? Rotom-h resists pixilate return, is immune to eq, and can just burn it while DD alt struggles to do much. For special mixed Altaria, Rotom-h also walls this completely since its immune to earthquake, resists fire blast and hyper voice, and can also burn it or discharge it for the paralysis chance. Its a way better counter to Altaria then lets say, Heatran cuz it dies to earthquake, or even talonflame because altaria can earthquake it if it roosts.
So yeah, move Rotom-h up to C rank at least please, but i'd prefer C+ because i personally think it fits way better with the pokemon in there currently n_n
