Lando at it's peak in Gen 7 has usage in the upper 40s.
It's that they're just annoying to play against.
Clefable has recovery and ridiculous utility with stealthrock, wish passing, heal bell, knock off, calm mind, cosmic power, and teleport, is psuedo-immune to status, is immune to stealth rock and spikes, can ignore boosting, and it's weak to very rare offensive types.
Defensive Lando was no where near as annoying since it could only take two or three strong hits, SD sets functioned exactly the same as every other offensive ground and had the same counterplay, scarf is easy to cuck with immunities and because they like locking themselves into scarf defog, and lead sets just killed themselves.
