Lies, I mainly played tanks and I picked her up because of the crazy amount of use I got out of her flying barrier. I could completely shut down snipers, block entire ultimates (killing Pharah with here own rockets), supporting Rein and Orisa when their barriers were close to breaking.
It was an excellent engage tool.
Symm’s teleporter is clunky, easy to kill, and has like a couple of places per map that actually helps your team ( often it’s not needed to get the job done anyway)
I could almost use that Barrier on CD and get massive value each time.
