These are probably some of the worst stats yet. Of course, Cresselia and Durant weren't around for the entire month so the stats don't really reflect that, but there should have been some improvement. Hitmonlee, Typhlosion, Dusknoir, Clefable, Sandslash, Tangrowth, and Feraligatr should all be used much less. It's a bit strange that people have been using stuff that was popular back in February and the spring, but it's probably mostly newer players using these things. If you want to know what's good right now, the
np thread is the place to go.
I think that a ton of players have been picking out Pokemon that look good at first glance, stats wise, type wise, etc, but not thinking about how they actually function in the metagame.
For example,
@Ghostbone, take a look at Munchlax. Munchlax looks like it would be a great Pokemon; it walls a ton of special attackers, absorbs sleep, and can phaze the opponent. However, in practice, Munchlax has very poor performances. It must rely on Rest to recover, and it does not have the benefit of Leftovers recovery. This makes it worn down extremely easily—even by the special attackers it's supposed to counter! (252 SpA Life Orb Sceptile Focus Blast vs. 76 HP / 232+ SpD Eviolite Munchlax: 161-190 (37.44 - 44.18%) -- guaranteed 3HKO). Munchlax doesn't even have any offensive presence, and Body Slam means that it will get set up on by Kabutops and such. Sure, it has Whirlwind, but Sleep Talk is unreliable and Kabutops can wear down Munchlax anyways since Munchlax is powerless. The "hate" for Munchlax IS justified.
Another example, Dusknoir. Just because Cofagrigus left the tier and we lack good Ghost-types DOES NOT mean we should automatically recklessly search for a substitute. There is no substitute for Cofagrigus, it was a unique spinblocker. Just because Dusknoir has high defenses DOES NOT mean that it is Cofagrigus's replacement. Dusknoir is a very poor Pokemon that cannot fulfill its spinblocking role against the most popular Rapid Spinners. Furthermore, Pokemon such as Rotom and Misdreavus have much more utility, and should be used instead of Dusknoir if you're desperate. Dusknoir just does not function well at all in RU and should not be #12.
This post is getting a bit long but I think I'll address the other Pokemon in my first paragraph. Hitmonlee should not be #7 because, even before Cresselia, Psychic-types such as Uxie and Slowking were extremely popular and Hitmonlee is useless against them, not to mention that it gets wrecked by priority such as Entei's ExtremeSpeed. Typhlosion is completely useless after it can't spam a Scarf Eruption anymore, which is nearly 100% of the time; with Stealth Rock and priority around, Typhlosion's Eruption will be weak, and its other STAB move, Fire Blast, is too weak to do any sort of damage to defensive teams. Clefable is decent, but should not be in the top 20 since it gets worn down easily in such an offensive metagame. Sandslash is as bad as always, it fails to spin against almost every Ghost-type in the tier, unless it is running the SD Lum set which no one is using. Tangrowth hasn't been great since Escavalier and Nidoqueen entered the tier, and I have no idea why it is still being used with Durant and Cresselia back. Feraligatr is another oddball—Grass-types such as Rotom-C, Lilligant, and Sceptile have been abundant, and Feraligatr no longer thrives in the metagame as it once did.
Hopefully people start reading the posts in the np thread and the Viability thread, because they really show what's good in the current metagame and what's not.
