Game favors camping

"Br has changed it wasn’t always like this"

I'm not really sure that BR has changed at all. I think what's happened is that a lot of players in the early days wanted to play BR exactly the same way they played all the arena shooters they came out of. And that worked to a point. But, as some YouTuber said, over time players will optimize the fun out of the game. Why run around trying to execute a lot of very high-risk engagements when you could just be patient, loot up, find your position, and wait for the final two? Is it lazy? Or is it efficient? Truth is, it's both. But what it also is very likely to be is successful. And people do what works. Or what the ranking system chooses to reward. I can't hold either one against them.

"it’s kinda been pushed to become toxic."

I'm gonna take exception to the use of the word "toxic." Cheating is toxic. Camping might be "irritating" or "anti-competitive" or "lazy," but I wouldn't call it toxic.

"I don’t see any of that being fun."

And there's the real argument in a nutshell, and I respect the opinion completely. I don't share it, but I've been playing long enough to know that different people find their fun in sometimes very different ways. I guess the problem comes when you can't reconcile game objectives with personal objectives. It's something I struggle with every day in every match.

"1 person does it and sooner or later everybody’s just sitting in buildings waiting for ppl to walk by or in"

I blame the ranking system for the times when it has favored placement over kills. I personally think that's what it should do, but I can also see how that's forcing people to play the game in a way that mostly sucks the fun out of it for them. Taken to its logical conclusion, the game would turn into exactly what you said: a bunch of campers waiting for the circle to close. Tense? Maybe. Fun? Probably not for most people.
