Sub 10k DMG as DPS, how can I improve?

hey! I've been playing Rivals since it released and I'm currently Plat 2 maining mostly Strategist. Recently though, I've started to play with some friends as a premade team and sometimes I have to DPS, and I find myself lacking quite a bit, finishing most games with less than 10k DMG (I can get more DMG playing as Tank or even some Supports most of the time).

I was wondering what are some tips you'd have for upcoming DPS players, I'd love to be versatile enough to play all roles decently whenever I need to fill for someone.

Thanks to anyone who helps!
