Kinda weird to me honestly. They already had the baton pass clause but apparently it wasn't enough. I feel as if Baton Pass has way too many weaknesses to justify a total ban (Especially with Nilego running Clear Smog at times) but what do you think? Was its ban needed or no, it wasn't.
Hell to the FRIK NO!
Baton Pass; although easily countered by Haze, is just to good and FUN! Smogon needs to rethink this whole ban of Baton Pass
Also, Clear Smog, Topsy-Turvy, and even Psych Up can foil an opposing Baton Pass strategy
Baton Pass DOES NOT have many weaknesses, in fact, is extremely hard to counter
1.- Nihilego should never run Clear Smog, is a waste of a moveslot in a Pokémon that already struggles with coverage problems even when using 4 offensive moves.
2.- Clear Smog doesn't affect users behind a Sub, which EVERY Baton Pass Team runs
3.- There are no Pokémon that run Psych Up in singles, is a waste of move, and a good Baton Pass team can play around it easily
4.- Topsy-Turvy is avaliable in 2 fully evolved Pokémon, one of them is Malamar (An unviable Pokémon that actually loses to any Baton Pass team) and the other is Smeargle (Which also loses to Baton Pass, and running that move is a waste of space)
5.- The only, actual "Counter" to Baton Pass is Haze, which is only run in 3 viable Pokémon: Toxapex, Mantine and Tapu Fini (the latter almost never uses this move anyway) Two of them get trapped an killed by Dugtrio, and all of them are easily pressured by Necrozma, Magearna, Latias, Espeon and Xurkitree, all of which are run in BP team
It would be nice if people tried to inform themselves before argumenting against something the have no idea about...
I don't think baton pass should have been banned. I think using multiple stat boosting moves and abilities on a Pokemon with baton pass should have been disallowed. For example, Scolipede with sword dance, speed boost and baton pass.
That's actually interesting, and was brougth up to discussion at some moment.
The problem with that is the fact that the ruleset would become MUCH MORE complex (check UltiMario's comment
