Why? Why! Why am I placed on the losing team80% of the time?

Because who is going to leave a winning team, the slot you took became free because someone rage quit because they were losing.

bro, you know,the matchmaking in Battlefield can be considered random — it’s just that you were unlucky and got matched into a lobby where people could leave the game.😘

serious question for you: how often do you play the objective? are on top 2-3 ppl on the board because you do play objective? if the answer is no well... that's why you are not winning. I would say on average my games are 50/50 meaning sometimes I'm #1 on leaderboard playing the objective like crazy and still lose, why? because EA catered way too much to COD community and so you have too much close quarter ultra low TTK and a lot of places to hide. Anyway, if you want to improve the win rate of your games this is the only advice i can give you: play the objective, objective is your primary objective and other things like kd, sightseeing, camping, vehicle play and destruction secondary. I cannot stress how important is for you to play the objective, also you have a map .. use it wisely, don't spawn in a place where all coddies are ..... spawn in a place that enables to be effective and take the objective. Play tactical not like a frag victim.
