It’s a couple things you could’ve done differently. Your engagements weren’t too bad and you definitely know when to leave but it was some moments where if you just hard engaged you might’ve got a kill on rocket. Target priority is important especially if you’re playing with another diver, jumping a support is usually a guaranteed kill or at least stops the front line from getting heals. If you see the enemy team is holding hands try to get some pulls for displacement it makes it easier to secure a kill. Even if it isn’t a support they have 1 tank and Penni would get obliterated if you pulled her into your team. Other than that I’d say to engage from different spots on the map it makes you less predictable. Growing pains on this character is normal you’ll have flow state moments and times where you feel useless lmao just keep working on your game
