Who to watch if I want to get out of Diamond

Ik the whole watch your vods and see what you did wrong but whose someone I can watch for more tips. I feel like watching radiant streamers sometimes is counter productive cause then I do things like the person on the other side is a smart radiant player, not a dumbass diamond jett one trick that swings everything and I get surprised.

watch y0y DSG and BLEED vods

what role? or more specifically what agent?
usually what I do is find one person per agent per map and watch a few of those

you have to be careful with duelists though, since some people just 'run it down' instead of making the 'correct' play

if i was diamond id rather focus on mechanics and aim than vods imo
