How do you get the 2016 Worlds Ultimate Team WE?
It was a mission or event reward. Riot's description in the client reads: “This icon was the highest tier reward players could earn for participating in the Worlds 2016 in-game festivities.”
Is the 2016 Worlds Ultimate Team WE still available?
No. Players earned the 2016 Worlds Ultimate Team WE by reaching the top reward tier of the Worlds 2016 in-game event. Riot does not rerun past events, so you cannot earn this icon anymore.
