Re: never getting a gun
You would only have this issue if you literally landed in open ground and ran around in circles for 10 minutes.
I think the reality is that you're not getting the guns you want,which apparently equates to "RNG SUCKS DO SOMETHING ABOUT IT" rather than just doing what everyone else does and expanding your ability to use any weapon in the game.
Alternatively you're just dropping at spots that simply can't accommodate a full teams loot needs and rotating badly from there onwards.
Either way it sounds like a player problem rather than a game issue to me.
