one death leaving could be resolved incredibly easily.
If they used a system such as bungie did for halo 2 , 3 and reach, that if you prematurely leave a game then you get a warning, then a 30 minute ban, then an hour, then 4 hours then a day.
And so on until it hits over a week,
one death leaving has systemically ruined most BR brackets above 9.3 and your entire match is dependant on people actually using a lineup rather than them performing well with said lineup.
The game time is 25 minutes yet most matches are decided with in 2 to 3 minutes and only rarely does it turn around to be a 10 minute or 15 minute match.
This is not a problem caused solely by premium players either as ive seen matches with people with top of the line tanks just leave after one death.
Then remove the stupid hoops you have to jump through to even get a game of sim in a vehilce you like.
Or make realistic true to its word and make it realistic.
