The survivor choice does not matter...

I agree 100%. Once you have all perks, survivors are just skins.

Either each survivor should have their own passive abilities, or you should only be only to put on ONE teachable from another character in your loadout. 

I'm petty sure it's intended that way. First because some survivors would be better than others and would always be picked. Second because the killer would easily know what to expect from them.

I think that in this way none of the survivors will be overall better than the others. They will just be able to perform better at their own part. Survivors know what to expect from each killer and play accordingly, so the opposite could bring balance to the game.

I don’t that it’ll bring balance to the game because every game I could message the killer my exact loadout and they can counter it directly and aside from nurse it would make minimal differences in how the game will play out. Mostly due to pallets,the gen rush, and swf.

I hope you enjoy seeing four Claudettes every game, because that's what would happen.

Actually, people would more likely pick Meg.
Meg could Get : Sprint burst 3, Adrenaline 3 and Self-care 1 (that still has 50% self-care speed, only a slight reduction on medkit efficiency)
Claudette could however only get Sprint burst 1, that could make the game slightly harder for them, which is not wanted ofc!

Well, it depends if you take Op's idea or WK5 idea tho.
Since Meg is a runner, she would very likely also get one of the best passive.

Personally, and I know this is just me, when I play Survivor, I will only pick perks that seem like that Survivor would be able to use based on their existing perks and their lore. It makes for some fun and interesting builds. I'd encourage more people to try it, but most Survivors only seem to care about what their most likely to win with, not have fun with.

Play 10 games survivor and 10 games killer and tell me your rank up percentage(do not do it, I am just saying). Since the killer does not know your loadout and you know his playstyle (killers instead of survivors have a unique playstyle), you have an advantage on him. So the game needs balance (lets not refer to looping,pallets, annoying survivor perks,etc.)

I don’t understand what you’re trying to say. As survivor you don’t know the killer playstyle until you are in the match. Even when you get in the match you may not know for a little bit because you can play against a Myers with scratched mirror or one with unlimited EW3 they’re not going to play the same. You also don’t know their perks until you’re in the game as well. Same with killer you don’t know survivor perks until you’re in the game. The advantage is very minimal if any. Pallet looping, too strong survivor perks, gen rushing,totem spawns, and swf are the big things that are causing the big imbalance we have currently. Every survivor should be unique in some way I agree but even if your suggestion was implemented it wouldn’t do much at all as far as balance goes. Besides you’d see 1 or 2 survivors all the time and I’m certain nobody wants that.
