I understand what you mean, but until shadowkeep rolls out there will be no major updates to the current state of PvP. There are lots of ways to have fun in PvP and it mainly starts with what outlook you are going to have. Get rushed by 3 people and die? Instead of asking why your teammates didn't follow your every move, consider how you got into this situation. Maybe you left your team and got kill hungry, or you were not in cover and just started blasting away. Never blame your team for death, blame yourself and find a way to improve. It seems that you are not willing to improve so you will continue not to have fun. I typically slap on a podcast and just turn my brain off in quickplay for fun and that is how I deal with the "broken" mechanics of the game. You need to find ways to not get mad in PvP. I typically just finish that game I was in and take a break.
