>>35434508>Unless its distribution is shrunk down to a few shitmonsLiterally the simplest solution the way I see it. Say, for example, only mons whose body contains literal detachable boulders could learn it. That leaves us with: probopass, regirock, gigalith, golem, onix, carbink, rhyperior, lycanroc, solrock and sandy wormadam (I hope I didn't miss any). Those are your options to set rocks now. None of them viable in OU? well they WILL be, because SR is still just THAT good of a move not to try and make the effort to squeeze the best out of that list (lycanroc suicide lead, gigalith as a tyranitar replacement, regirock for the bulk and sturdy, etc.) into your team. Stuff like omastar, sandslash, skarmory and such? they could still learn spikes. Stuff like chansey and clefable? they have absolutely no bussiness learning any hazard move that currently exists. Reducing the distribution of powerful moves to a few obscure mons forces players to pick more carefully instead of just sticking landorus into any team which is what we currently have. It has no impact in-game, at least that I can think of, since normal players don't usually sit there and spam SR against gyms.
Making it only last 5 turns is a fairly reasonable solution tho, not gonna lie, although I stand that distribution is the key to balance.
