High key she's the best support because of her rez ult and the dedicated healing. A great Lucio is great, a zenyatta that understands he's a snipe healer and needs to hang back is great too but it's hard to top a dedicated heal bitch.
I swear to god Symmetra was much better like 4 or 5 betas ago. Idk what changed, maybe building ult meter was faster, maybe her turrets were better but shit definitely feels like the most useless character currently. You see a good Symmetra now and your first thought gotta be wow my team is garbage.
