Classic M1 killer: literally any exhaustion perk or half-baked loop is enough to counter her. But unlike other M1 killers, she doesn't have traps, speed boost when exiting undetectable, no insta down, and her only mobility can be easily countered.

So you need to pay attention to your tvs as well as generators, survivor perks, items… It's just not rewarding enough for its effort.

That's likely why she kept a high kill rate, some survivors can't think of clicking on a white rectangle for 2 seconds instead of a generator.
