This game.
I can't figure out who I like the most. Just started clicking with Wraith after being Caustic and Mirage most of the time. Wraith's ult in a group (I'm with randos most of the day until friends can play) in a group that pay attention to whether I'm placing them... is fun as hell. Not sure about the Mirage and Lifeline, could have been in a Party together, but zero was communicated via mic. All pings.
If you know how to place them/read them (including the eye or "I'm watching this location") you don't even need a mic to win. That said, surely a fully mic'd and communicative team still has the advantage, but damn if Respawn didn't make a lot of really smart decisions.
So what are some practical uses for Wraith's portal?
In that winning match above, there were three times were we were getting into fights with multiple teams, or a 3rd party would show up as we were engaging our initial target. Each time I put a portal down, and we escaped or rotated on one of the teams to put THEM in the middle of two teams. It was fun fun fun.
The match immediately preceding that one I had both of my squad mates leave the match the second they were crated, and I killed the squad that pushed us only to then be alone...
The match immediately after the match above, the circle was still HUGE with only us and one other team left. Took forever to find each other.
