Not every unit is phosphex rapiers. There are plenty of ways to force status checks cheaply. Hell almost every vehicle in a marine army list can take a Havoc for 5 points to fish for stunning. Every tech priest can take a grav gun, aux have a billion ways to spam multi lasers, this isn't hard.
Status won't work every time but if you've brought enough you can tag every infantry unit your opponent has deployed, at that point you'll be slamming enough status to debuff a portion of his army every turn.
Sure you do want to be able to kill shit but this doesn't have to be an either/or scenario. You CAN do both and it's gonna work better than focusing solely on 1 over the other.
