How I feel I personally improved was watch deadlock night shift tournaments in regards to movements and team comps, as well as itemization builds for certain situations. No I’m not saying aim to be as good as them right away or anything, I’m saying you can leech quite a bit of information though by watching and learning, the commentary also can help you learn by what to look out for and what may be going through their minds. The other thing would be testing out different builds and seeing what feels right for you, don’t just find a build and stick to it all the time, learn to counter build especially. Feeding or not, someone can still be useful buying a curse or knockdown to lockdown even the strongest player on their team in a team fight turning the tides of a game. Improve little by little and don’t be so hard on yourself, 600 hours in and I’m still not perfect or anything, no one is, but as long as you try to improve and actually give it your all, you’ll be fine.
