As much as I hate to say it, Wraith is probably fine where she is. I was a Wraith main for the longest time but the way she was used in the first few seasons...what the developers said was true. I only used her cause she was an absolute get out of jail free card, which is not fair when you can’t do this with anyone else.
The developers also said in their Wired interview that Wraith is supposed to be like a gnat. She’s not supposed to go in guns blazing but be a distraction while the rest of your team takes them down.
Which can be rough if you have bad teammates or a team you can’t communicate with, but then it’s more about bad communication or lack of communication than it is Wraiths abilities. I stopped using her cause you don’t always have teammates that will allow her to be used the way the developers want her to be used, but I’m okay with that. The same can be said about Crypto’s buddy Hack. If your team doesn’t follow in right behind Hack your outcomes have a higher chance of being unsuccessful.
