Hi there,
I just had a game against Ashe in Stadium, she was able to get some ultimate charge by shooting herself specific spawn-rooms where you can leave the « healing area ».
She was shooting her dynamites, she even took the perk to get several of them to take even more damage. This combine with the 50% reduce B.O.B, she was able to get an entire ultimate after 5 seconds into a fight.
I reported it in game, but I think it’s also interesting to report it here so it can be fixed really quick.
Thank you for the help you can provide on this topic !
