I have a guess.
Based on the recent trailer, people are assuming Wraith can perform short ranged teleports as her travel power. I’m guessing that’s accurate. I’m also guessing that some of her main abilities incorporate this, a bit like how Goliath can leap normally, but also do his special leap smash.
So, two of Wraith’s abilities that we have to go on by name are “Warp Blast” and “Abduct.” I’m going to hazard a guess that Warp Blast involves Wraith teleporting to a targeted destination or enemy, and upon arriving releasing a blast of energy. Likewise, I’m going to guess that Abduct involves Wraith teleporting to a targeted enemy or location, and then grabbing her enemy and teleporting back to her point of origin, carrying the hapless foe with her.
What this means is Wraith will probably have light armor and health, but be built around the idea of exposing herself to as little fire as possible by making extremely quick-hit-and-run attacks. The hunters are camping the generator? Wraith watches from a distance, then teleports in, sets off a Warp Blast, unleashes some Decoys (whatever they may be) to draw fire, sets off some Supernovas (whatever those are) and then teleports out. Or she teleports in, Abducts a hunter, teleports out, and then goes to town on the lone hunter while his/her buddies try to rush to the rescue. The hunters can’t stay at the generator if there’s a monster just out of range that keeps zapping in to let off explosions before running off with one of their friends.
In other words, if Goliath is all about getting up in the hunters’ faces and staying there and Kraken is all about keeping his distance and raining death from above, Wraith is all about darting in, doing a ton of burst damage, and then darting out again before anybody can hit her.
