Killer is unplayable without ruin
There really is no winning without it unless the survivors are wasting time. You find 1 guy on a gen and hit him once if you are lucky. Now to actually down him you'll be forced to chase him through 8+ pallets while the others are popping gens.
If you give up the chase to pressure gens then the cycle just repeats. You hit someone once and then have to chase them. Meanwhile 1st guy is off hook and healed if you were even fortunate enough to catch him.
How do you win as a killer against smart survivors? It really seems you can't unless they make a series of mistakes that let you win.
