Not liking class systems is fair, it is a pretty big shift. Dunno what to say then, I'm sure there's a shooter out there with tankier players, I don't know if there's one that also has the same map size, permadeath, and other such things. I don't play many shooters though so I may be overlooking something.

At some point if you're picky enough your only options may be getting into modding and/or being unhappy with your gaming options most of the time. Who knows though, battle royal games are getting big, there's gonna be a few year lag before the market gets fully flooded with them but once it does maybe something will fit your exact needs.

I wouldn't personally want pubg to change. Since getting knocked down instead of instant death is a thing and its hard to hit targets I've had plenty of extended firefights, and the fact that death can be so sudden and you're often running through open terrain hearing distant gunshots and praying they aren't aimed at you adds a horror-like element, I love that its trained me to fear things like fields and bridges. I wouldn't want that to change, but I can totally understand it not being universally appealing.
