Best way to counter Bastion ? Ideas ?

bastion is one of the easiest heroes to counter atm, actually all "attack" heroes can deal with him especially if they havve mobility with the best beeing hanzo and tracer. With hanzo you just sonic arrow the bastion so your whole team can see him and then u can 1 shot him with scatter arror, or peak back and forth with normal shots. As tracer you can charge your ult quickly and basiclly often time you will have a free kill when u ult on a bastion in sentry mode making it a 5v6 for you team
