I guess I'll go on a replying spree.
The reason they don't want to ban ice scales is because without it, nothing stops special attackers. You can be like "YOU GOT BLISSEY" and sure, you got blissey. But what happens when you've got a life orb sheer force adaptability and whatever the hell else you want to stack is on 3 mons at the same time? There's no special intimidate, no special wisp, nothing. You've just got a single normal type pokemon that gets worn down decently quickly, even if it is just PP stalling the softboiled.
Is the meta stale? Yes. I'm not trying to meta bash, but Inheritance is going to be a very stale meta no matter what you do. Some abilities are just better than others. You ban those abilities, new ones come in and become the new norm, with almost no downtime in between banning and the next obnoxious threat, be Offensive or Defensive. Although we're making the right steps into making shared a healthier metagame, it's an infinite staircase. Once we ban all of the broken stuff, the meta will no longer be fun or creative, but until we do, people will be forced to run said broken stuff constantly.
My opinion; this meta is hard to take seriously. I've been grinding on the ladder with an Immunities team, and believe it or not, it's the most creative thing I've seen on the ladder for an incredibly long time. A meta like this is supposed to make you look at something and be like "huh, that's really cool how they got that to work so well together," not "it's another Stamina/IceScales (or a SkillLink/Technician core)." I don't think there's enough time left in the month to make it a healthy and fun meta, and after the month's over almost nobody's going to be playing it anymore. The meta has an amazing concept, both in simplicity and creativity, but when executed it takes out the creativity and leaves only the simplicity.
