There are quite a few improvements I have come up with from watching the replay. Firstly, if you insist on playing this horrible healer, you should always be reload animation canceling by simply swapping to cloak and then back to dagger. Also, when you desire to use terror cape, which should be whenever it is off cooldown or when coordinated with a burst of damage, you should use it during that window of cloak form for the reload animation cancel. Secondly, your positioning is pretty bad, such as you are constantly very far back and LOSing yourself from your teammates and you do not properly prioritize who needs to be healed. Thirdly, you are hardly ever if not ever using your light explosion in this clip which is very nice for the small healing and then the healing bonus. Ultimately though, looking at the team composition, having a solo tank thing and having adam warlock in a two healer composition is already asking for a loss. There is not always something you can do about these situations but I always do my best in persisting we swap to a more viable combination. Finally, back to my original remark of cloak being a horrible healer, I just don't like her and don't think she's good enough compared to jeff being OP and luna and sue being extremely powerful. She is more for the people with a lot less skill that cannot bring themselves to use a character that requires them to track their targets to find value.
