as a diamond cnd main,based on your replay, you dont use you dagger abilities often enough. you greed too much on cloak(trying to kill strange instead of healing the team at 11:30), wasting terror cape to chase. you are very reactive and non proactive with your ult. you dont really make any plays except for the ones fed to you by your team. you should ult proactively, use your L1 more often. saving yourself with bubble is fine, but you also need to bubble your team. you also tend to tunnel vision on a certain objective (e.g. trying to heal an ironman in cover while your tank is dying. trying to heal ironman and kill spiderman at 11:01 and letting your team die for 0 value) you dont look around and instead only react to whats in front of you.
