After playing more games are learning more, I now realize that you have to control where you get domed as wraith. Preferably an underground spot with low visibility. Using this you can wait for the hunter that is ahead of the others and burst him down, and as of right now wraiths ability to take on 3 hunters stage 1 is too much and stage 2 it s free win.
And it is the combo of supernova and decoy, this can get 2 hunters to half hp. Add in a warp and well now both of them are at about 300 hp and a cleave auto does around 250. Hit your abduct and your golden.
There should be more emphasis on being able to isolate targets and then bursting them down rather than being able to take down 2 hunters at relatively the same time when their cds are down. Especially when those targets are the medic and support. If I can get a hunter down before the fight begins at stage 1 I can get at least another strike and then dart away maybe losing one bar of hp. Stage 2 if I get a hunter down before the fight and I’m domed its over. Decoy plus supernova all I have to to do is evade and wait for their abilities to go on cool down. Frankly that’s a little too easy.
EDIT: Putting it this way, if there are 3 hunters and I use supernova and decoy. I focus the medic, I don’t know what my decoy is doing. I look back and see that the decoy did half the supports or whoevers hp. All I have to do is warp that hunter and then abduct the last hunter and the game is over.
