Hey we've been teaming 5 and we all beginners and actually weren't be able to answer this question. Does that really makes sense? Action i am asking is like reviving a teammate with little to no money in order to save gun.

I figured it out guys. Since other Phoenix takes on entire teams, they clearly come from the Smurf dimension. They can't invade as a team since riot would notice and ban them so they attack the Low Elo world in 1v5 games. Change my mind.
