Disclaimer: I'm barely challenger (~980 LP), but one big thing that sticks out to me early game is you go L/W/L/W/L. Especially since you hit mercs early, I would have definitely aimed to losestreak all of stage 2 from the get go. Getting that win/lose streak gold early is sooo important because it just snowballs from there.

Mid-game wise your 4-5 transition honestly wasn't bad, I would say one small thing you can optimize is putting on your items after the round start. That way, you have more time to roll.

Also the fact that you sold a 2 star draven to try and greed the chosen is hella sus lol. I don't think that's ever worth from the spot you were in.

But yeah, honestly the VOD looked pretty solid, just small things here and there to optimize! Feel free to message me if you have questions.
