No Wraiths Portals Outside the Ring?

Wraith's portals disappear  in just a few seconds when used outside the ring......why not just let path finders zip lines dissolve outside the ring too?  I feel like there was no reason for this, if a wraith is setting a portal to get her team inside the ring, chances are her team is already pretty damaged when they do make it out......if this nerf was because of the ability to set a portal into the ring to loot death boxes (that your team probably worked for and deserved the loot in the boxes anyway) i think its honestly kind of ridiculous. Wraith isn't that powerful anymore compared to other legends. Allow her to portal outside the ring please.
