Ok I lied, I ended up getting to this sooner than expected so here are the updates:
Swellow added to C-
Hitmonlee up to A+
Uxie up to B+
Alomomola down to A
Pelipper up to C+
Escavalier up to A-
Rotom-C Up to A-
Some things:
As I was going through updating the list, there were some Pokemon that I wanted to move around, but I'd like some discussion on them first before I do anything.
Jellicent to A+:
Jellicent is probably the best bulky Water-type in RU right now (I never thought I'd say this). Between countering Cobalion and being a great Reuniclus check, it's kinda hard to build a team and not use it. Unlike Alomomola, I feel like Jellicent is a lot less exploitable because it can deal damage and because of its access to Taunt to keep itself from being statused and set up on. Jellicent's flaws basically boil down to being: susceptibility to Pursuit and weakness to Knock Off, but Jellicent's decentish Speed, Will-O-Wisp, and Scald help it get around most Pursuit trappers, so I feel like it's not that big of an issue. Hex is also a really cool option on it as well if you have something else that can deal with Houndoom and other Fire-types to a lesser extent; 110 BP Ghost STAB with the added on burn damage does a ton even without investment.
Durant to A:
With Jellicent, Noivern, Steelix, and Cobalion being particularly ubiquitous right now, I don't feel like Durant is the hottest pick for teams atm. The Choice Scarf set is still good vs offense, but it's STABs don't exactly have great coverage and a Choiced Superpower isn't the best thing to be locked into, so it's a bit prediction heavy as a result. The meta being particularly fast right now coupled with the fact that most defensive teams use Jellicent means that Hone Claws set has a bit of difficulty breaking down these teams or pulling off a sweep.
Tyrantrum to A+:
This is the Pokemon that punishes your team severely for not including a Rock resist and is one of the best Choice Scarf users and wallbreakers in RU. It contributes a ton defensive wise also, courtesy of being a great Fire check and Flying resist. I don't think Noivern and Glalie being so common affected it as much as was anticipated, considering Choice Scarf is the best set as of now; although its Choice Scarf set does face a bit of competition with Flygon, it has much more power and considerably more spammable STAB move that still makes it a threat even against defensive Pokemon.
Feel free to discuss the above and nominate other Pokemon to move/up down. If you disagree with any of the changes, you're free to say so as well.
