[2020] If being at 35kg+ is going to start having negative effects on the player then strength should start leveling there.

I don't know how they played this and thought it was okay, in order to actually level strength you need to be 60kg+ and at that point walking drains stamina and you have to sit completely still for it to recover. There's no feasable way to level strength through movement, you either have to buy tons of nades or melee a friend a bunch. It makes it feel like the game is punishing you for actually running great so all this is doing is encouraging people to do pistol/low gear runs so you can actually loot and not be super overweight.
