pathfinder does seem similar to wraith, but in a vastly inferior way.
tactical - both can be used to flank. pathfinder's tactical provides more options for moving fast and traversing terrain in unique ways, while wraith is hard to see and takes no dmg.
passive - wraith's is incredible. pathfinders is meh. This game is about aggressive skermish combat. Knowing the next circle is nice, but not amazing. I suppose if your goal is to be stealthy at getting into the final circle while avoiding combat it might help, but then you don't have the gear to win it. Moreso, this doesn't even feel like a passive, because the *only* time you can activate it is at a tower.
ult - wraith can portal out not only herself, but her entire team, along any arbitrary walkable path, and nobody can be shot during the traversal. pathfinder can make a zipline to advantageous high ground, but if you get on it in view of the enemy, good luck as they spray you down off the zipline. This is especially true if you are moving directly towards or away from them.

I'd really like to see pathfinder get a better passive. the "next circle" discovery could stay (it's not really a passive anyhow), or it could go. i don't really care about it.
here are some ideas:
1. he could always see the next circle (without towers), and use towers to *change* the next circle location... this would make his passive more of a real passive that he benefits from all the time, not just when he goes to the towers
2. he could "fold up" to get dmg and hit box reduction while zipping on ziplines (and possibly during his tactical) -- which would fit well with his ult and lore of swooping in for the kill - pretty useful all game long
3. he could take damage form the zone at a lower rate -- he is a robot after all
