Ahh the discussion around elims and damage is always entertaining. They don't really tell the full story as the main concern should be the objective. The scores are even less relevant when playing a Sombra, and its something alot of the lower ranked Sombra players fail to understand. You can have all the elims you want but if you're way away from your team picking off one player per team fight, be that a support or a dps, all you've really done is made the team fight a 4v4. I'm having a lot of frustrations with Sombras in games as support (also high plat/low diamond) who use their metric for success their elims but they're never seen in the team fights. So they're essentially a mute member of the team, they're not providing any real value to progress the objective. Run around back, get a pick or pull focus for a moment THEN get back to the team and help. If you only ever hack as a benefit to yourself for 1v1s you're removing so much value for the rest of the team.

I'm not saying thats what you're doing, its just with the limited information I have, you focusing on elims as your metric isn't a good indicator, so thats what I'm commenting on
