Because apparently having fun playing the game is not enough these days, you need to add a meaningless meter that can only go up no matter how bad of player you are.
I’m lvl 37 now and from time to time I encounter people expecting me to singlehandedly carry the team to a record time victory. Totally coincidentally these are the same people that are first to leave when the first objective falls quickly on defense or has some problems on offense.
When I reach lvl 57 I will be expected to also carry concurrent games on neighboring servers
