Okay. You know how I said that I thought the tierlist was fine as it was? I lied. It's stable, but there are some things that I want to address.
I also recommend that Landog is moved below M-Kang, to show that M-Kang is better. I think we can get away with this because it's not worth creating a S- rank, and there's only two Pokemon currently in S-Rank.
A+ -> A: It's still the powerhouse it is, but due to the high popularity on BS, practically every team has at least one check or counter to it, if not two. I feel that a drop is needed to represent the fact that it's still a massive threat, but not as effective anymore.
A -> A-: In a word, overhyped. Not too much, but it is. While still worthy of a ranking in the A's by far, and would probably be one of the better A- 'mons, it's really crippled by burns and paralysis, is weak to a typing that's on almost every team in Psychic, and is prone strong attacks + double-targeting, as it relies on Leech Seed and Giga Drain for recovery.
A- -> A/A+: How is this thing so low-rated? I recognize that it's weak to the common Ice- and Steel- type moves, but it's easily one of the best redirectors, with the ability to go offensive, defensive, or a mix between the two, good supporting moves in Thunder Wave, Tailwind, and Air Slash, and great offensive STAB typing. It can fit on a multitude of teams, all of which would appreciate its abilities.
: What's the reasoning behind this ranking? I'm 100% unfamiliar with Chandelure, and I'm not going to argue it's placement until I know something about it. I just want to know why it's ranked where it is.
: Not going to recommend any change, but just saying that I believe that since Politoed is practically synonymous with rain teams, that Politoed should represent the ranking of the entire Rain archetype, as it will be present in 99.99% of all Rain teams/archetypes.
: ...why is this ranked? what does it do that Rhyperior doesn't? Does it survive anything with Eviolite that Rhyp can't?
B- -> B+: Prankster Tailwind, Encore, and Taunt, plus access to Beat Up for the TerraCott combo and Memento for an immediate advantage when it's job is done, lets it fit in a lot of Speed Control teams. There's a reason why it's so popular. It's certainly not A material, but also certainly not B- material.
B- -> B/B+: extremely fast Rock Slide, fast Taunt, access to Wide Guard and Tailwind, and the unique support STAB Sky Drop makes it a great supporting attacker. It's biggest downfall is it's frailty, and the fact it really wants Focus Sash. Enough to make it raise a ranking or two IMO.
C+ -> somewhere in B: With Water being so commonplace and so many high-tiered Pokemon not really enjoying it, Storm Drain is a great supportive ability. It seems to be a supportive attacker to me - bulky, doing too much damage to be called chip yet to little damage to call it an offensive threat. It also has access to Recover, so it can afford to forgo items like Leftovers and Sitrus Berry for more offensive choices like Expert Belt. Certainly not C worthy.
C+ -> B/B+: I'm sorry, but I just don't see why this is so low on the rankings. While Fighting Gem was a great asset to it, it was more luxury than anything else. In my opinion, it's big claim to fame is its supporting-attacker abilities. It has access to Fake Out, Wide guard, Quick Guard, Feint, Intimidate, and a Close Combat that's still strong without Fighting Gem. Its defenses aren't horrible, either, with high Special Defense and Intimidate. I agree it hates Status, that its defenses aren't stellar, and that it doesn't like going against anything that resists fighting STAB.
D -> C/C+: Hear me out. Yes, it falls over to any hit. Yes, 89 base speed isn't the best. However, it's the only Pokemon with access to Tailwind and Sleep Powder (which is effectively a Spore), as well as the only sleeper that can hit Grass-types super-effectively, and actually hit it hard due to the ability to spam Hurricane. It's also one of the fastest Sleepers in the tier, outsped only by Pokemon with the unreliable Sleep Powder, making it the fastest reliable sweeper. No higher than C+, but not D material.
I know I didn't explain everything in too much detail, but I didn't really have that much time to spare. I could elaborate on a nomination later if someone wants me to.
