I was talking about VGC too, so maybe we can put aside the "real format ; )" dig
....
Also some of the usage stats I'm seeing has it as a top 3 or 4 for a lot of months and never below the top 20. I think still managing top 15~20 usage by the end despite Incineroar is still, like, you know. Pretty damn good actually. Actually even better considering how the meta had shifted in general from new arrivals
If we're talking of VGC then you know as much as me that Lando-T had usage but not really that much, due to basically demanding Dynamax to do anything + being basically useless once Rillaboom or any grassy terrain setter was in.
Sure it was around, if anything cause it also helped checking Zacian, but realistically speaking speaking, it had nowhere near the omnipresence of the past.
Lando-I on other hand has had 0 usage (not exactly surprising, I don't think it ever had any, even now with HA allowed), which is why it got buffed.
I doubt it'll get any nerf this generation either. The simple fact that Iron Bundle is near guaranteed to see play, on top of still not having a reliable flying stab + not having a ground stab that doesn't hit its own partner (no, Earth Power doesn't count) will turn it in another case of "either commit the gimmick or don't use" which is not something you want.
That said, at least for now, it's the best source of Intimidate present (I don't quite count Gyarados or Arcanine as good in that regard, while they do provide Intimidate, they require much more support to be usable), so it's very likely to see play once allowed either ways. However, with Clear Amulet and Covert Cloak being a thing, thus bolstering more intimidate-immune pokemon & less way to flinch your way to victory, I wouldn't be surprised for its usage to also drop again once DLCs come and a bigger part of the dex is around.
Honestly I don't get the hatred for Landorus nowadays.
I can understand OU players being tired of seeing it everywhere, after all, even in BSS it still had ton of usage due to not having the problem of EQ being spread or having to fear the very common Icy Wind, but I don't recall VGC players having any complaint about it. Mostly cause they're too busy complaining of Incineroar who took its place.
