"Annoying" is subjective/opinion, but Knock Off and Poison Heal are objective parts of the kit if being evaluated on performance in this Meta, where throwing out Spikes via that longevity is a more significant benefit than previous games of "sit here and don't die" for Gliscor if Toxic didn't work. Gliscor gaining hazards in a meta with bad removal and mostly Physical neutral-attackers is its old kit performing significantly better than it did previous. This isn't even me advocating stay vs ban, but you can't just write off mechanics of how a mon-as-a-whole plays as irrelevant just because they were pre-existing. Several Pokemon banworthy in one Gen became not so later, and the reverse is equally easy to see happen.Knock and poison heal with immunity to status should be irrelevant. Being annoying in OU should be irrelevant. If this is where the discussion is, then this Mon should have been talked about since x/y days lol.
