Remember no matter what heroes we choose to counter Symmetra, we have to give respect to what she does. All static defensive heroes exploit irrational aggression, and quickly turn frustation into out-right anger. Systematically and precisely destroy Symmetra's nest, working with teammates. If the enemy team is hunkering down in and around her nest, actively seak to avoid it and flank the enemy team using the other paths of each map. Symmetra is static in nature, while she counters mobility in her nest, using mobility to by-pass her setup can be just as devastating as destroying it.
Hard Counters for Symmetra
Junkrat (Low-Medium Difficulty)
Important to keep in mind when spamming: 1. Pros and top Junkrats only use 4 of the 5 grenades to ensure they have 1 left to answer incoming threats. 2. Vary angle and distance to vary the ending location, this allows you to catch heroes as they run like crazy from the grenades that are incoming; it also make it hard to predict what is actually a safe area to stand.
Pharah (Low-Medium Difficulty)
|Arrows Represent sniping angles and avenues to exploit jets|
Pharah is a staple choice for the attacking side (or defending side if Symmetra is using her Sentries on the pay-load). Rocket spam, Vertical mobility, Knock-back potential, Pharah comes excellently equipped to disrupt and destory Symmetra's feeble creations. Remember to always save one rocket in your clip while spamming, similar to Junkrat. Exploit vertical aspects of each map to maximize your punishing effects on static defenses. Plan usage of your Concussive Rocket to isolate targets, or escape near death situations. Lastly exploit the effect of being able to pressure from multiple sides at once, accounting for 2 angles of pressure will always be harder than accounting for just 1!
Reinhardt (Medium-High Difficulty)
Soft Counters for Symmetra
Roadhog (Medium-High Difficulty)
Hook is game breaking to deal with for heroes like Symmetra. Because Roadhog has such a high HP pool, there is no way Symmetra could kill him after being hooked. Factor in that all 200 HP heroes die in one primary fire and quick melee, Symmetra will be forced to actively avoid where Roadhog goes. Chain Hook is much better than most realize at first, having an almost 22 meter distance and 6 second cooldown, it is both spammable and effective at medium range. Add in the minor 30 damage it deals when it connects, and Roadhog is a pick generating machine. Hunt Symmetra down, find her defenses and hook her out of them for easy kills. Use Roadhog to generate power-plays with hook (where its 5v6 or 4v6 because of picks) and cement that tempo into objective time.
Zarya (Medium Difficulty)
