Personally for shield bash a saw a really good idea so i’ll list it here.
Shield bash now prevents movement and disables all mobile abilities (capture the flag rules basically)
The no movement effect would last the same amount of time as her stun does, obviously this replaces the stun.
I think this would be a really good change, she would no longer make reinhardt drop his shield and would still counter dive heroes while being less effective against heroes like mccree since he could counter flashbang because it doesn’t stun.
