Wraith is all about burst damage. She doesn’t do very well in long, drawn-out fights since she has so little health and armour.
With regards to comps, I’d say you either want a defensive comp (Hank/Sunny, Val/Caira) to protect teammates from the burst. However you’d need to make sure your medic/support are able to keep themselves alive since they will become public enemy #1.
Alternatively you could take a damage comp (Cabot/Kala/Bucket, Slim/Papa/R.Val). Wraith does not have much health at all. Capitalise on that. You’ll probably take some strikes along the way but with the damage you’ll be outputting, that Wraith is toast.
Wraith struggles with destroying deployables, so characters like Bucket, Emet, both Maggies etc can prove a challenge for her. Abe/Crow with their stasis can also be very annoying.
Make sure your always with 1 other person. Wraith can burst a lone hunter down very fast. If your going to split, do splits of 2. Stay within 20m of your buddy and you won’t get stacks. If you do have 3+ stacks, stick with your support/medic because you are going to be a juicy target.
Always be ready to boost backwards when you go around a corner. Wraith could be waiting to ambush your abduct you. Save that jetpack fuel for when you really need it!
