t's REALLY annoying that it can take up to 5 minutes to get in a match and land.

Must be your internet or location. I only have 20mbps max internet and takes seconds to find a game.

Exp is only gained if you stay until your team wins or dies. If you leave while team mates are alive you recieve 0 xp

my internet is 650 mb/s and still cant even see the enemy before they kill me makes the game really stressful to play

The matchmaking time is tied to your geographic location (i.e which server you're on) and the number of other players on that server who are also searching for a match at the same time.

It does not relate to the speed of your connection.

And as someone else said, (E)XP is awarded if you kill people, do stuff, survive etc and do not disconnect early.

cant kill anyone half of the people i come across are invisible can't shoot at anyone therefore cant get exp? stupid game
