I would really like to see Widowmaker buffed on consoles. I've been struggling with how to do that without just upping her damage, which could break her like she was in pre-patch. Right now, she's just an insanely difficult character to use that to the point that it almost isn't worth it to get good with her.
So I have 2 suggestions.
Give her grapple a shorter cooldown. Maybe as short as 1 second. Widowmaker needs to be more mobile because right now, as soon as someone knows her location, she's almost certainly dead. I think this is fair because Widowmaker is not only prettty squishy, but also has more limited area awareness, since she's going to be looking through her scope most of the time, so in most cases, people will get the drop on her. This mobility would not only give her a decent chance of escape, it would also let do her job more easily. She's supposed to be someone who moves positions to get better vantage points, so it'd be good if she could Spider-man her way around.
Her ult is really helpful for the team as a whole, but not so much for her. Knoweledge of where a player is coming from is great, but again, the difficulty in her aiming means this only helps so much. I propose that her ult also give her markers over the heads of enemies. You know how when Soldier activates his Ult, enemies get
those marks over them on his HUD? How about when Widowmaker activates her ult, she gets similar markers, and if she hits those markers, then that counts as a headshot. It's the best way to actually boost her ability as a sniper I can think of.
