Since we're trying to make solo queue as strong as premade groups

BHVR doesn’t see these changes as survivor buffs but instead just QOL (they’ve explicitly stated as much). Therefore I wouldn’t expect any killer buffs in response.

For example, his traps are now deadly, any survivor stepping into it, dies instantly. That would make him as strong as Nurse lol

It doesn’t matter how many buffs you give killer they will never be as strong as nurse.

How would you even buff them to make them strong while still keeping there identity? Twins are getting reworked next but sadly they might get the Freddy, Doctor treatment where they get completely redone.

And people are already saying knight needs a rework

He doesn't need to be Nurse level, but he should have been allowed to start with all of his traps a long time ago. Setting speed should be 50% faster and bag base carry should be 3.

He also needs his diamond thong cosmetic from Hooked on You. I've never seen it and only heard vague rumors about it, but my imagination has made me very naughty.

This complaining is starting to get out of hand. There are plenty of problems in DBD, but the new HUD isn't one of them. It's not the same as comms, and most perks designed around denying survivors information are unaffected.

You do kinda conveniently forget about something there: killers pick rate is usually disproportionally high during the weeks after release. Every killer has an extremely annoying aspect. Not everyone capitalises on that extremely annoying aspect but if you run into the killer a lot then you will also run into the annoying things a lot - and are more likely to complain. Usually, there is a point reached where the frequency is low enough to warrant no more than an eye roll. It doesn't make certain mechanics or add-ons or synergies any less annoying or OP - it's just less of a hassle to go gg next and move on.

To OP:

That being said; if the remaining 2/3rds of killers (wherever that number comes from - but let's assume that's exactly how the numbers are for the sake of the argument) are pushed to Nurse/Blight level (not that I know how - let's assume that's possible) it would result in killrates exploding and in all killers getting massive nerfs and survivors massive buffs until the killrate is right again. Which, tbh, I think would be a good thing in the long run. Certain killers/perks bottleneck balancing the killer side atm. Just like the Solo/SWF is bottlenecking the balancing on the surv side.
