Umm, how about she can’t heal herself? So you just kill her, and if the second enemy healer isn’t looking after her shes toast.
Moira and Brigitte are meant to shift the meta, and make it so there are more options that just the same heroes. It would make sense that you can’t dive on a healer meant to counter dive…
She has counters, and if you can do damage to her or separate healers or what have you. She is meant as a mid range character and the shield slam is both defensive and offense, because if they use that or miss with it than they are hosed and can’t do anything for a few seconds.
Just like if you group together on moira’s orb instead of being lone wolf genii they don’t do as much damage. Yes there will be balance changes, but there is a reason they are doing this, its so every match does not consist of tracer genji winston dva etc
