I honestly don't know what you guys really want with her anymore. She literally got nerfed every single time except for this one. She's just fine as she is now. Everyone remembers her tinier hitbox but also everyone seems to forget that she takes more damage than any other legend, so you need less bullets to kill her. In a 1v1 situation and your enemy is another legend you're basically done unless you have a noob in front of you. I really don't find any more difficulty to kill Wraith compared to other characters. As an example Gibby has a much larger hitbox yes, but he takes less 35% damage. Every legend has its pros and *, it's up to you to make the best of them. Stop blaming Wraith and start improving your aim, you'll see that she can be killed easily.
As for pick-rate, every game has its favorite character, you can't expect a completely equal situation, so get over it.
