You are almost never where you should be, even if you’re healing the right targets. You GA in front of your team alot, waaaay further than any mercy should go. Ignoring the lack of scouting and the heal/damageboost bot play style, even at 0:20 you end up in front of your orisa barrier. Competent dps would have smoked you right there.
At 1:45 You tunnel vision in valk, damage boosting your orisa who is doing nothing but contesting point, instead of damage boosting or healing your pharah to allow her to secure a pick. after that you go battle mercy instead of going to heal your orisa, causing her to die. You get the rez off, using the barrier as cover, but then position in front of a hanzo and then fly off the map???
You should have been far away from the hanzo once you rezzed the Orisa, considering that you could have superjumped/slingshotted past your orisa. After that, you push in without your maintank, which although you win, is a bad habit.
3:00 After that teamfight, you go behind a pillar, and try to juke mccree shots, instead of flying to your orisa and being completely safe behind a barrier. You then walk INTO a hanzo dragonstrike, which means mccree can one shot you right there. You win the teamfight that comes after, but that teamfight could have been flipped on it’s head if you had gotten killed there. You generally position in places that will get you killed because you’re next to a mccree or in front of your orisa’s shield, which just means you lack awareness.
