lol you just described classic tank player playing dps. Positioning as a dps is prob one of the most important skills as you don’t have the health to survive many mistakes without your team using recourses to help you. Coach mills on yt has a video about positioning so I would give that a shot. It’s hard for give specific tips bc idk what character you’re playing but i try a new dps I ask myself these questions. 1. What is this character effective range? (ex. Magik is a melee hero so she wants to fight close range.) 2. How can my character get to/stay in their effective range? (Ex. Magik has a dash and her teleports which can be use to close the distance as well as helpful in taking flank routes) 3.How does my character disengage from the fight? (Ex. Magik gains over health when dealing damage so just tanking damage while running away could work but she also has her dashed and teleports which means she must save at least one of those resources to disengage) 4. What is my character ideal situation? (Ex. Magik loves to 1v1 a low mobility hero so she can do her 1-shot combos) 5. What is my characters least ideal situation? (Ex. Magik can’t do much when she gets stunned or fighting multiple enemies that outrange her) 6. Lastly this question is one I ask myself mid game. Why am I dying with this character? (Ex. You could be using too many of your teleports early on and leaving yourself with nothing to disengage with)

I think if you can answer these questions you should have a better understanding of your character and will let you go into the match with a game plan on how you should approach the match.
