[2019] Just got the game! Need some advice to play better

So I just got the game and was wondering if there's any advice you guys might have. I've played BF1 for about 6 months on and off and I've never been that great at it... I was just wondering how BFV takes a different approach to combat and stuff would like any advice you may have for new players or things that are different than BF1 and need to be kept in mind
