Please don't make Unbreakable basekit, at least make it available once per trial.
BEhaviour has been making a lot of amazing changes recently and that's coming from someone who's been very critical of how the devs ignored the many issues plaguing DBD.
The changes to the Progression system were great, the bloodweb isn't very costly and very rare add-ons are actually rare now. The ability unlock perks for all other killers at Prestige 3 feels very rewarding.
Some strong survivor perks like Dead Hard and Decisive Strike have been nerfed but also decreased the chances of survivors escaping the trial, that's another issue the devs will have to find a way and balance (At least Borrowed Time is now basekit and kinda counters camping or tunneling)
Which bring us to this upcoming PTB update. I don't want to be dramatic or anything but this new update could completely kill DBD.
Making Unbreakable basekit infinitely will make snowballing and comebacks almost impossible for killers like Oni or Twins, it would be a better change if survivors could pick themselves up only once per trial without any perks like Unbreakable, Soul Guard or Boon: Exponential.
Mori being basekit would be a good change if it only activated once the gates are opened, the killer gets to Mori any survivor who gets downed during the endgame collapse, the killer would feel more terrifying during that time and survivors would not want to stick around.
But I just read the Developer Update and if I understand correctly, the Mori will be automatically be performed one the last standing survivor who gets downed and all the other downed survivors get sacrified automatically, so no more being able to use Unbreakable to get up after all your teammates are downed or on hooks, no more getting up to find hatch or crawl towards it.
I think this could make DBD very unfun, a lot of high MMR killer players will try to instantly down all survivors to automatically win the match, survivor players won't get a chance to escape if their last teammate goes down, Sabotage plays will become more common, perks like Unbreakable & Tenacity will become meta.
Hopefully these changes end up being good for the game, I've recently been playing DBD consistently and I really don't want unbalanced mechanics to make me not want to play as much anymore.
