>>50804301I fucking hate Lando as a design, but I will still defend it not getting uber'd. It's not overcentralising, it's versatile, there's a big difference.
Overcetnralizing means that the mon in question has a dominant strategy, and you subsequentially need an answer to that strategy to beat it, which limits you. Say, Zacian alone can just click a button and see most OU teams die one after another. Unaware Quagsire can put an end to that, but including it makes the team weaker to things that aren't Zacian. That's overcentralizing.
Versatile mons like Landorus-T are baisically a dozen different mons in one, that's where usage comes from. It's not overcentralizing because every Lando set in a vaccuum is perfectly beatable by reasonable means, you just have to guess which one it is, which team preview helps a lot with. In fact, it is actually self-limiting, unlike most mons you might want to have multplle Landos because it's good at so many roles, but you can't have more than one and have to settle with something else for the other roles.
