DS needs hook nullifier
It is beyond stupid easy to turn ds into the perk it was once originally by exploiting capabilities of it being on a timer. It rewards bad plays as in farming in-front of a killer. You pick up the farmed survivor you get ds'd you down and pickup the unhooker you get ds'd. So either way their perk gets used. It needs to nullify ds on hooks.
I would suggest to balance out the timer being nullified by hook. If the DS user is downed before someone else is hooked. They get to keep ds as they were tunneled down without a chance.
