I had a 4 stared ( or prestiged or whatever you call it ) Junkrat and a 5 stared hanzo lure me into a trap just to solo ult me cause I outplayed them as Junkrat
Possibly, but it was also a meltdown of bad plays by the moira wasting her ult on one mei and to leave her team without the support (and ult) she's supposed to be providing.
