Kangaskhan is as certainly more manageable now than it was last season, however, it is no way less S rank than it was last season. Kangaskhan's only buff on the transition between VGC 14 and VGC 15 was Low Kick, a move which lets it reliably OHKO bulkier Steel-types and opposing Kangaskhans. Will-O-Wisp is far less prevalent this season than it was last season, so this argument is less true now than it has ever been. Intimidate is a real factor which must be considered when running a physical attacker, and yet the metagame is predominantly physical. Intimidate arguably hurts Landorus-T more than it hurts Kangaskhan, 140 base Attack is bigger than Kangaskhan's 125, before you factor in Parental Bond which takes Kangaskhan's actual Attack stat somewhere around 200. On top of that Landorus-T's is reliant on spread moves which deal even less damage when intimidated. So Intimidate while a legitimate argument is irrelevant as it affects all physical attackers, not just Kangaskhan. There are two maybe three relevant Ghost-types, Aegislash, Gengar, and maybe Jellicent. All three of these Pokemon while good have very exploitable weaknesses, while Kangaskhan can't handle them they are all able to be dealt with relatively similar Pokemon. This means that Kangaskhan requires minimal team support. While saying any Pokemon needs team support is generally a reason for them not be S Rank, Kangaskhan is more than capable of providing offensive support for the Pokemon which support it. This is a far more symbiotic relationship than most other Pokemon which require team support have. Landorus-T requires far more support arguably than Kangaskhan, because of it's reliance on Choice Scarf or Choice Band the move that Landorus-T locks itself into can be capitalized off of. Assault Vest while more capable of taking hits, is both slower and generally weaker which diminishes the reason to use Landorus-T in the first place for more durability. Landorus-T can't just be slapped on a team, Earthquake hits you're own Pokemon. You need at least one other immunity to Earthquake on your team for Landorus-T to be a other worthwhile pick.
I could use these points to make the argument that Landorus-T should be A+ rank, but I won't because Landorus-T is an S rank Pokemon. Every Pokemon has flaws, however, Kangaskhan's and Landorus-T's consistency and their shaping force on the metagame can't be denied.
The three changes I want to see in A rank are:
Politoed A ==> B+
Ludicolo A ==> A-
Azumarill A- ==> B rank
Politoed only exists on one play style, and even then it is being used more for its ability. Politoed isn't a good Pokemon, Drizzle is a good ability. While the Drizzle and Politoed are effectively one and the same, it balances out to rain being a match-up based play style. Because rain is so match-up based, a rain team has to be able to play without rain and thereby Politoed. This redundancy on its own play style is really what limits Politoed from being A rank for me.
Ludicolo on the other hand has usage outside of rain, being able to take on relevant Pokemon such as Rotom-W, Heatran, and Landorus-T. This support value can be capitalized on outside of rain by Pokemon such as Mega Salamence, which appreciates all of these Pokemon being taken care of. Predominantly found on rain Ludicolo should be ranked similarly to Politoed, however the support value on teams which aren't using rain is reason enough for it to be ranked a little higher.
Azumarill is very underwhelming. While Huge Power, and an excellent typing are definitely strikes in its favour, overall it is lacking the consistency it had last season. Last season a Belly Drum sweep was hard enough, now that amoonguss has a harder time it even harder to sweep. The main Pokemon which the Assault Vest set dealt with have also dropped in popularity, resulting in AV Azumarill being far less capable in many of the common match-ups. While certainly usable it is by no means an A rank Pokemon.
