BHVR should use the PTB far more liberally outside of major updates.
There are currently things in the game that are arguably not worthy of an updates on its own yet very debatable, perks and mechanics like Gen regression, Bear Trap mechanics, Insidious, WGLF, PGTW, etc. should be tested in the PTB.
In order to solve that BHVR should update the PTB for small yet focused testings.
Example:
Week 1: Bear Trap rework: Replaced RNG with a channel, to see how long the channel should be and how perks and addons could affect it (ONLY TRAPPER IS SELECTABLE DURING THIS PERIOD)
Week 2: Insidious rework, all players get multiple versions unlocked by default to test out.
Week 3: Gen regression, regression is increased to see how it affects playstyles and how it can help against the gen rush.
Week 4: WGLF and No Mither, multiple versions...
Week 5: PGTW is now token based, to see how it would affect the Killers behavior and its usefulness in general.
Of course this means small surveys have to be set up regularly and players should be rewarded with iridescent shards to incentivize playing the PTB.

I wish they would get a little more liberal with the PTB to test some more drastic changes just to see what would happen.
Even if it was just number tweaks since those would require very little work.
There's a couple issues with this:
Not to say that using it more is a terrible idea, but it just doesn't work well if it's always on with minimal changes. It's much more efficient for us and appealing to more people if we put a bunch of changes in at once.
The only reason most people don't stay in the PTB is they can't find lobbies... TAKE out KYF's and have NO rank in the PTB or reset it make everyone rank 20. GIVE everyone 1mil BP's too. It's not like anything you do in the PTB goes to live anyway.
Removing KYF from the PTB might be counterproductive. If I'm having a hard time finding a lobby as is, getting a couple friends together to test might be my only option. In the example of testing killer perks, this would be even worse since the majority of people would want to test as killer.
We are able to "disable rank" in the PTB though; last time we ran a PTB the game would accept any rank.
