Sounds like a good thing to me. It may be that none of these things make a difference, but it's worth trying them all and comparing each approach. I applaud them for at least experimenting with different combinations and solutions.

And if none of them are working, then BHVR will have to do further investigations into why players don't want to play Survivor (if that is actually the case). I think it's partly beacause the Survivor side is under developed and not novel enough when compared to what Killer offers to players, but there might be other reasons too.

Personally, I did notice a small improvement in Killer queue times but obviously they say they have data that shows it's not been impactful enough. I've heard arguments that Killer queues would naturally get better if the mode became permanent and players didn't feel like they all had to rush to play Killer. That may be true, but I'm not sure that's an experiment they could realistically carry out.

I don’t understand the rationale behind continuing to test with bots. There has been overwhelming feedback that people do not want to play with bots, period. They said that bots didn’t help enough to shorten killer queue times, and one bot is going to help even less, so why even have that one bot? Just get rid of them altogether, which is what most players have been asking for. It’s very unfortunate that it took a huge amount of community outcry to make this happen. The mess could have been prevented from the start if BHVR would have listened to everyone who was telling them what a terrible idea it was.

There is currently no evidence people don't want to play survivor other than people who don't like survivor in 2v8 telling us that nobody likes playing survivor as if it is a fact. I enjoy survivor in 2v8 and the fact you can instantly getting 5 other people (7 before the bots messed with the matchmaking/lobbies) at any time of day or night, often even faster than you could find 3 in 1v4 strongly implies otherwise. There's just significantly more killers proportionally, which is all we do know.

When queues take 15 minutes for Killer and .00001 seconds for Survivor, there's something wrong with the role.

If Survivor in 2v8 is not appealing, no amount of BP is going to change it.

Thing is, during the first version of 2v8 they only had the 400% Bonus on the 2v8 queue, which was not enough to bring enough Survivors to play 2v8 to make Killer queues bearable, but was enough to pull them from 1v4 so that Killer queues there were also unbearable.

Going for a different approach now is better. You will also get information if Survivors play 2v8 for the mode or the BP-Bonus. So if the queue times get even worse then during the first version, it would show that a) back then the BP-Bonus was a big reason to play and b) 2v8 most likely got worse for Survivor. (Both things I would agree with)

One of the biggest core issues of 2v8 Survivor is that it lacks the appeal that 2v8 Killer has.

Killer has unique synergies between different Killers and Classes that make it incredibly diverse and interesting. We've seen Killers interact in ways with one another that was not previously possible, and as a result, it has created a lot of situations that not only help advertise the gamemode (clips, videos, etc.) but serve as the focal point of attention.

The only way to make Survivor keep up with this is provide more Classes and Interactions between Survivors.

It needs to be as, if not more, interesting than Killer. Introducing Classes that are not as boring as "heal faster" or "do Generators faster" can significantly help, since the Medic, Guide, Scout, and Escapist classes are decent but only serve to cover the "fundamentals" while lacking the appeal of being interesting or catering to niche playstyles. Furthermore, introducing more ways of interacting with Survivors in the gamemode would also serve as a good way of providing further incentive to play Survivor.
