Game Health For Both Sides

So recently we've seen quite a few improvements to the game, notably for the killer side. I wanna talk about something which maybe doesn't worry me but interests me to say the least in where the game will go from here.
With the most recent mention in the latest Q&A that DS is being looked at, there sure are alot of good QOL changes happening to killer. I mean what else is there that rlly needs a change on the survivor side? Keys? Being reworked soon. Haddonfield and other annoying maps? They will most certainly be changed with their graphical updates. Now I think this is a good thing, becaues it symbolises pretty niche balance which is coming to survivor, especially consdering how broken it used to be.
What I'm wondering about however is balancing on the killer side. I mean there hasn't rlly been any major changes to some of the broken stuff on the killer side. Sure Pyramid head got a change, but it hasn't rlly affected him too bad. I mean currently deathslinger and spirit are still in the game in their current form, undying has no major plans to be changed soon, quite a few maps are full of extremely unsafe areas. Clown and demo's potential changes are also quite scary, buffing clowns bottles could make him very opressive in chase and an addon pass for demo could end up with him having some insane charge addons and becoming the next deathsligner.
Is this a problem for the games balanace and future? I know survivor has had some insanely broken stuff in the past and killers have and still need buffs in some essences, but is it going to far now? Has an invisible uno reverse card been played which we don't know about?
