Overwatch - Every Hero Ranked From Worst To Best
21. Symmetra
Symmetra's defensive capabilities simply cannot be denied: she can set up six Sentry Turrets at once, so protecting an objective is a piece of cake. She can also protect allies with a Photon Shield and her Teleporter Ultimate Ability is enormously useful for upping the pace of battle and not wasting precious time running back to the objective.
Still, her Photon Projector isn't an especially decent weapon, she can be cut down in battle with ease by most other characters, and though the Projector's charged energy ball can cause huge damage, it takes so long to fully charge that you'll probably get killed before you can use it effectively.
Not the most exciting character, but as even the "worst" character, she can be pretty useful from time to time.
