Winston raising his gun over his head with two hands, like Planet of the Apes when they raise and shake their sticks. Or like the Tusken Raider in A New Hope.
There ya go, free great idea Blizzard.
Wasn’t even that difficult.
EDIT: While I’m at it, take the snicker emote for Symmetra, trim it down to just the middle-ish frame, and blam, Victory Pose that shows her gun. Win-win again.
