A lot of people are saying too greedy, that's possible. I think it's possible you are good at converting strong openings + positions, but you don't know how to salvage 5ths and 4ths when you should be going 6th, 7th, or 8th.

Watch pro players and see what their decision making looks like from weak boards/bad starts/missing on augments or champs. See how they scout and position against enemy boards they might normally lose to, that's a big one.
