Good evening, Earlier today i've been in arena of glory and i encountered 2 people teaming up against me, I would please you to watch as careful as possible and understand that the attacks on each other are just to cover themselves from people like me, Every time i respawned they would just both go on me with all they got, there are some moments that you can see on the video, they stop attacking each other and both turn on me at the same time, there are other moments where they don't even attack each other, and just kill mobs so they can throw me off from finishing 2nd aswell, with the link of the video i will provide a screenshot too, so you can see these guys are on the same legion
