I've been in touch with UU system for a little bit while I was on hiatus x hiatus, and now that I'm back, I've been playing a good amount while also reading info on the meta in threads. At first glance, I thought the vr was solid but, after some games (about 20) I'm now questioning certain rankings. I'm not 100% on my opinions right now, I just want to speak my mind and see what other people say.
Gliscor S rank? - I'm not sure why Gliscor is ranked so high. I understand that it has amazing techs in roost, defog, stealth rock, swords dance, and toxic stall; all paired up with poison heal. But to me, this meta is extremely fast-paced, and I don't think Gliscor has a good time handling it. Sure, Gliscor is great against stall, which is fantastic right now but, Hyper Offensive teams are getting better too & I don't think Gliscor matches up well against it. Rotom-W, HP Ice Mega Mane, Offensive Azumarill, Z Latias, Z Serperior, and SD Facade Heracross are all threats that are on the rise; each one having good usage. Just to add on, it does fair pretty well against U-Turn Hydreigon (which is awesome right now), chubby/hard-hitting sylveon, Mega Bee, and A-Muk. So to me, I would think Gliscor should be A+ or A rank; it handles one half of the meta with ease but, struggles with the other half. Sure, you could argue that it can grab momentum really well with stealth rocks, toxic, swords dance, and defog while healing from poison but, I feel like there are so many pokemon that grab momentum too while also providing a lot of other stuff to the table too. I guess I could see that it's S rank due to it's weird stats (not including SpAtk) when paired up with the coverage, techs, and ability. What I mean by weird stats is that it has a high defense stat (which means you barely have to put EVs into it), average attack & speed stat(you can mess with the EVs to better fit your team), and barely average HP & SpDf stat (which means you can still manage with it to live neutral special attacks). So with this, comes a lot of unpredictability in the favor high end players that know the meta really well. Gliscor's stats and movepool + ability may seem like awkward shit but, to a well-seasoned player, they can automize a set to perfectly fit their team's needs while, also catching other players off guard. This doesn't work perfectly on ladder, as ladder is random as deadpool, but it's perfect for tourneys. So, just to put emphasis - I'm not saying Gliscor should move down, just questioning its current status in the meta.
Mega-Altaria A+? - I don't think Mega Altaria fares this well in this meta to claim such a high ranking; in my opinion, I would say A rank or A- rank. The thing is, Mega Altaria has 4MSS and trouble with EV placement (EVP?). A lot of the times you want heal bell for the plethora of status abusers in this tier, Fire Blast for Omnipotent Scizor, and EQ for random bulky fire types that pop-up. Now, for EVs you want max speed for scarfers, max attack to ensure KOs, some EVs in HP because HP is borked, EVs in Defense or Special Defense to get up another DD if needed. It's just confusing for the DD set. For support sets it's also weird, as you're not sure what moves you want for whatever situation that might arise since Mega Alt can handle a lot of situations but, also come up dead without the right move. You want Fire Blast for Steels, Toxic/Return to speed up the process, Roost, Defog, Heal Bell, etc. It can be unpredictable but, it can also be unreliable so, you could bluff one set but if they guess right then you're busted. Also, not sure that it deals well with Hyper Offensive side of the meta, or the Stall side of the meta. Making the 4MSS even stronger. Even the EV placement shenanigans (EVPS?). Now, the same thing I said up there but, replace Gliscor with Mega Altaria.
Mega Manectic & Rotom-Wash in A+ rank - I seriously disagree with this. I really think they should be in S rank. Mega Mane is a near perfect Mega for the Meta/Hyper Offense; while, Rotom-W is a fantastic support mon for the Meta/Hyper Offense & Balance. Mega Mane fairs well against a lot of top threats, has the ability for faster threats that don't have a strong attack stat like Mega Aero (-1 252 Atk doing 64-76% while T-Bolt is guaranteed KO). Not to mention it has Flamethrower/Overheat for a quick knock out against Scizor, Serperior, and Heracross (while doing good damage against Mega Aggron). It also HP Ice for L-Rod M-Sceptile. Obvious Volt Turn abuse comment. Just an outstanding mon to say the least the least. Sure, it has trouble vs Stall as Quag messes with it but, it can HP grass for Quag, as Overheat does do big damage against M-Sceptile. Rotom-Wash is great with Pain Split, Volt Switch, Hydro Pump, and Defog. Just a really great set that heavily deals with the fast-paced meta at hand. Balance isn't that good at the moment but, Rotom-W really does help to push it up to make it viable. Pairing very well with Moltres, Scizor, Latias, Infernape, and many other threats. Just absoultey stellar with support, and offensive pressure. It handles HO & Stall fairly well; pain split + volt-switch (brings in trappers like Scizor) is super annoying for Blissey. Although I really want to see these 2 move up, I don't know if I really want to nom them just yet; these are just my thoughts for now.
