Black lock/hatch rework.

Hatches are kinda cheap in there current state. I've played to may rounds where a survivor brings a key+blueprint addon then just bail out to the hatch when things don't go there way completely avoiding endgame. The blue print addons should be changed to very rare i know the keys are but its actully very easy to farm keys with plunders instinct and appraisal ill find a key 4/5 rounds sometimes multiples in one its ridiculous. With that being said I think there should be added black locks to the game that are on chests contaning ultra rare items and added structures/loops with a locked windows/pallet. Then keys can be acquired in game by completing certan objectives. Like mabye have a key behind a gate that opens when a certain gen is completed but doing that gen first might set you up for a 3 gen. Then comes the hatch I think the hatch should have 4 blacklocks on it but one gets removed every time a suvivor is sacrificed/escapes. This would make a suvivor have to unlock the hatch end game but with added keys(mabye 4) to the trial I think it would balance out and add a more objective focused play meaning if a suvivor knows there not winning the trail they should start looking for a key and ration the keys properly provided there's 4 per trail meaning 4 suvivors cant use the hatch and open other blacklocks unless more keys are brought in. P.s keep the hatch noise for the last suvivor.
