			Crawdaunt--> Low B-Rank: The best offensive DD user in the tier. While it is very slow, most of the foes that try revenge kill it get OHKOed by Crunch / Waterfall on the switch. It requires some support, but is very decent overall.
Dusknoir--> Top D-Rank: Actually a pretty good spinblocker. It only has a small chance of getting 2HKOed by Kabutop's Stone Edge (assuming No SR or SD boost) and comforably beats Cryogonal. Its not amazing, but its not as bad as Ninjask.
Butterfree--> Mid D-Rank: Why would I ever want to use a slow, frail SR weak pokemon who hits like a sissy without any boost? 9 times out of 10, lilligant is the better QD sweeper thanks to its better bulk and lack of SR weakness.
Rotom-N--> Mid A-Rank: Amazing typing, allowing him to check several threats in the RU metagame. Shadow Ball and Thunderbolt get amazing coverage in RU, only being resisted by 3 foes (and all of them take a large amount of damage from HP Fire). It isn't very Bulky, but its unique typing gives it a solid place in mid A-Rank imo
Ferroseed--> Top B-Rank: Ferroseed is a very useful pokemon in the current meta. Its unique typing allows it to check no-HP Fire Lilligant, Druddigon lacking Fire punch, Rotom-N and several other threats. It also gets some amazing support moves like Thunder wave and Spikes. Its not the best pokemon in RU, but its still pretty amazing.
		
		
	 
 
Crawdaunt I can agree with, not for your reasoning since Fraxure, Feraligatr, Altaria AND Shelgon are better at using DD than Crawdaunt, and pokemon are "revenging on the switch"? Do you know what revenging is? The fact is is that Crawdaunt has amazing power, and is fairly slow and frail. I would say he hits like a fucking nuke, which is what people were saying about Zangoose and why he should stay in 
Top A whereas Crawdaunt, who is slower but bulkier, doesn't have consistent damage chipping at him (I say consistent but it actually increases over time) and has a way to boost his lackluster speed is down in Top C? I would say Crawdaunt belongs in Top B at the very least using your Zangoose logic, and if not then 
Crawdaunt --> Mid B.
 
Dusknoir I can't agree with. He is bulky. He can use subpu- oh wait no. He has priori- oh wait so does Spiritomb... Dusknoir is not a /bad/ pokemon he is just otuclassed in absolutely everything you would ever want it to do ever. 
Dusknoir stays in Mid D, arguably Mid D --> Low D. Also Ninjask is Mid D?
I want to propose 
Ninjask Mid D --> Top D, one of the best supporters in the tier and capable of pairing up with all physical cleaners such as Aggron and Bouffalant (I tried a bouffalant+ninjask cleaner set and it was fabulous, I didn't even use SD on it and it worked). As one of the best supporters and baton passers in the tier I would dare say he belongs in Low C but for now Top D is fine.
 
Butterfree going to Mid D? Let me get this straight, you want to move Butterfree BELOW or even EQUAL to Dusknoir? That is absolutely hilarious - HILARIOUS. First of all how the heck is Butterfree out-classed by Lilligant? Butterfree is not out-classed in any way... The problems with Butterfree is its frailty so it can be difficult to set it up, does that make it as bad as Dusknoir who is literally dead-weight all the time? No. Just no. Butterfree deserves Mid or Top C rank, so I am actually going in the completely opposite direction to you and say 
Butterfree for Mid/Top C Rank.
 
This may seem liek I am disagreeing with you for the sake of it but Rotom-N (let's jut call him Rotom) is simply not good enough for Mid A. He has two viable sets, defensive subsplit and all out offense. This makes him awfully predictable once you see it use one move. He is not powerful enough to plow through teams like an offensive scarfer should and can't even manage a revenge much of the time. The fact that you will be locked into a type with an immunity if you pick a STAB attack frightens me from using it since it would require a whole lot of switching and prediction, or support. In terms of his better set, and ironically the one you did not mention, SubSplit, it is an excellent set. However once again you are either having your only offensive move immune to Normal or Ground types, two very common types in RU. These downfalls mean 
Rotom-N stays in low A.
 
I agree with Ferroseed though, but I am tired of making this post so I will just say 
Ferroseed ---> Top B
