I don't know?
Maybe people are getting ready for boots on the ground / CoD WWII and that's why.
Maybe it's just me, but it seems like IW of today has way more campers than how IW was being played months ago.
It's been like that for a while, the game was pretty fun and fast paced for me all year then I started doing Black Sky camo in June, I finished at the end of July and wanted to start playing normal and going for nukes again. Holy 💩, the whole world started camping in core and hardcore. Id almost take NV4 hardcore camping over noobs squatting in corners with duel wield models in core. I'm not really sure what happened, maybe people just gave up on improving and decided to camp.
