.Recycle's main abuser is Bronzor, if we had the latest mechanics, Dark and Ghost attacks would be super effective against it and it wouldn't be as dominant as it is currently.
.While Stuff like Ponyta/Growlithe/Larvesta/Taunt Vullaby deal with recycle Bronzor, hazards + double swtiching make it really hard to punish bronzor. The implementation of Heavy-Duty boots would greatly solve this matter.
Doubt it'd happen anytime soon, but one can hope i guess.
