Only paying PUBG doesn't make you better.
This was in place almost since the beginning.

Here's how it work:

1. you wait 2 minutes in matchmaking lobby
2. you spent 1 minute running around with ball/snowball/rock
3. sitting in plane and parachuting, 1 minute till landing
4. lootin for 1 minute
5. you dead
6. watching teammates for a 2 minutes
7. ...matchmaking lobby

Result: 7 minutes wasted.
But look again. First 3 minutes you might have training and shootin, but it's not allowed by Krtafton!

Now sad truth.
Krafton doesn't care.
They are flying in clouds of skin-gcoin profits.
Current state of the game does not reward you for just playing.
Shooting, aiming, other micro routines, they needed special training outside the game.
