Apparently atleast ange1 is supposed to be joining Navi

First of all, bang was known for his insane Raze, Reyna and Pheonix plays. He was "forced" to play Astra for TSM and I think that was part of the reason he was benched after so short period of time. Second two duelists isn't meta anymore, especially when a player like Subroza is on the team (playing Skye most likely).
