Haven't posted here for a while, but there's a few things I'd like to see move:
Garchomp for A+: simply put, chomp is the best suicide lead for HO teams (Azelf is a very close second). It has good bulk, typing, and power, which allows it to set up rocks 99% of the time! even without a sash. Additionally, it has Swords Dance, which, when paired with a Lum Berry, allows it to beat many bulky waters 1v1, as well as Sableye. However, the reason why it should move up is its bulky set. The bulky set is incredible on bulky offense teams, as well as some balance. It punishes physical attackers like no other, and it sets up rocks against any non special attacker. On top of this, its a great check to Heatran, Lando T, and Bisharp, all very threatening mons in the meta rn. It can even take on non IcePunch gross 1v1, which very few mons can boast. Chomp at the top of the pack for A mons and I feel its time for it to go back to A+.
Mamoswine for B+/B: Mamoswine really took a hit post Mence ORAS, and it honestly isn't that great in OU. Good, sure, but not on par with other A- mons. I'm not very adamant about this change, so if I see a good reasoning for it to stay, I wont argue against it. Imo, it's only viable set is the LO attacker, because Sash Lead is too easy to counter lead from my experience. The LO attacker is good for taking on genies, Lando T, Dragons, and Gliscor, but I find it is often let down by its mediocre speed. Mamoswine is no longer the anti meta monster it once was, and I feel a drop May be necessary.
Azelf for B: second best suicide lead for HO right after chomp. Taunt, speed, boom, and movepool are all it needs to be effective. It also has screens, so it can do that if a team needs those. It's offensive presence is also pretty good, as fire blast is a good move to roast steel types that May try to absorb the boom. Speaking of boom, its a great way to ensure that you maintain momentum, as it gives you a free switch and blocks Defog / spin from slower things. However, Azelf is fairly one dimensional, so I don't see it rising higher than B.
Camerupt for C: talked with AM about this briefly, but I feel camel needs to drop. It's speed is just too damn low. It's power and bulk are good, but it is quickly worn down due to the fact that it is forced to take a hit before it can attack. Yes, the ability to 2HKO most of the tier is awesome. However, this is rarely possible because it's forced to take a hit before it can get off the hits it needs to actually achieve this. C+ is a little high for a niche like this! and a one sub rank drop isn't out of the question.
Ditto for unranked: this thing is just bad. Whenever it's in team preview, everyone knows what its gonna do. And it's not like it's terribly effective at it either. It's forced to run a scarf, and can only get one kill per match, if even that. It's a wasted teamslot 99% of the time, and there's no reason for it to be ranked. Whatever "niche" it has is not enough for this thing to be on the viability rankings. It's worse than Donphan. Yes, Donphan.
Haxorus, Tornadus, Gourgeist-Small, and Noivern for unranked: grouping all these together. They have no niche.
Haxorus's Mold Breaker Taunt is done by Gyara, and the mega slot argument is invalid because Gyara is that good, and Haxorus can't even make use of that taunt because of its frailty. It also has to run poison jab if it wants to beat unaware clef, which is a suboptimal move in OU because you're forced to forego EQ.
Tornadus is just bad. Torn T is better in every way and prankster rain dance isn't enough of a niche to keep it ranked. Thundurus and Klefki do that better while systematically having other uses. Remove it.
Gourgeist Small is 110% outclassed by XL. The speed means nothing when its bulk is really bad due to that low HP.
Noivern has no niche. Hydreigon, Latios, Garchomp, torn T, Mega Pidgeot, and Gengar all do what it might try to do, but 100% better. Ninja is rip, so it being a dragon that beats it is no longer a thing. Hydreigon and Latios are better wallbreaking special dragons that also go one step further through either breaking balance, or defogging. Garchomp is a better attacking dragon too because it, too, has other uses other than attacking, such as bulk and sr. Torn t and Pidgeot both do the hurricane thing better, and their speed is more than enough for the job. Torn t has bulk and power and regenerator, while Pidgeot never misses. Gengar does trick specs better if you really wanna go down that route, because Gengar actually has power behind its attacks. Unranked this thing please.
That's all for now. Might post on what the slate is later, but I needed to bring these up.
