I glossed over the reason for STag in my statement about BP. Because someone would have made Wobb work, or Gothorita, or whatever, so to avoid furthering the problem, the core of the problem was removed from the game. Since apparently it needs to be repeated, complex should only be done when they need to be. Dizzle alone is not broken, Politoed with Drizzle is not broken, a lone swift swimmer is not broken, Drizzle toed + a swift swimmer however was. Because Drizzle is not broken and Toed is not broken, but the combo between two seperate entities was, one of the few complex bans we have ever pushed was created. That wasn't a precedent, it was an exception. If King's shield proved broken on another mon, there would be no argument on what should be done, but we all know it isn't. So why entertain it? The answer is easy "so we can keep Aegi". That isn't how this works.I actually explained why Kings Shield is completely different than any of those other stuff that you mentioned that quite frankly you're straw manning. Why not just ban Politoed instead of Drizzle in gen 6 lower tiers, or Shadow Tag when only Gothitelle back in gen 6 abused it? It's because we know meta relevance and if a Pokemon can provide extremely useful niches in a metagame like Politoed in PU than it's more beneficiary to keep the mon than to just ban it as a whole.I'm not answering past this if you can only pull up something I spent 3 paragraphs rebutting while you brought up the exact same stuff I stated with nothing new about it. It just annoyed me enough once to actually state it.
Also I think Aegislash as a whole should stay, I'm just giving a middle ground for people who think it's dumb, when honestly I view him as a really solid Pokemon and that the metagame centralizing around it is better for teambuilding and the competitive scene as a whole than "diversifying."
