This is the first round of RU I've played since Cresselia was banned for the first time, so maybe I don't have as much perspective on the subject as the rest of you do. However, I'm going to go ahead and share my thoughts on the topic. I am of the opinion that Cresselia isn't a centralizing force in the metagame. There are plenty of Pokemon that can deliver serious damage to Cresselia (Escavalier, Druddigon, Spiritomb, Drapion, etc.), and almost every team carries one of these threats. Of course, if you fail to pack something that can deal with Cresselia, you arent going to be able to stop Cosmic Power Sigilyph either. So its not like Cresselia is forcing every team to carry that one Pokemon just to stop Cresselia and vice-versa. I've found that the best way to deal with Cresselia is by inflicting it with Toxic and setting up on it. Cresselia cant do much to stop SD Drapion, CP Sigilyph, and others from boosting up and sweeping through its team. Taunt is another option that shuts every variant of Cresselia down. So is it difficult to deal with certain variants of Cresselia? Of course, but not any more difficult than dealing with CP Sigilyph, who we have already deemed unbroken. I like Cresselia's presence in the tier, and I hope we keep it in RU for future rounds.
Also, I have found Durant to be completely non-existant on PS (someone please correct me if Durant is not supposed to be used on PS RU!). Durant is somewhat lost in the offensive nature of the meta, being outsped by Sceptile, Manectric, Galvantula, Archeops, etc. Its base speed really hurts it, and with its lackluster coverage and vulnerability to priority, I would not consider Durant for any type of team except Hyper Offense. Just my thoughts on the topic, please let me know what you guys think!
