Just like how it's annoying to see gens pop super fast but makes total tactical sense to split on gens, do some gens first, or do gens as fast as you can as Survivor to win - especially against fast Killers - it's annoying but valid to have SOME amount of slugs and early outs too.
It only really becomes an issue when you're seeing slugs left forever, or seeing Killers consistently go after the same Survivor for being Sable. THEN it's toxic. But if it *makes tactical sense as pressure*, then that doesn't need a punishment. It's a valid tool, as valid as gen splitting is.
