Will there ever be a 4 player squad mode

@Thi3f-U I'd say it's unlikely. Apex was built around trios, the designers wanted the teams to lack at least one legend class, so that players would be pushed to cover that missing class with skill. Also, communication and strategy become more difficult in larger teams, would be too much for the regular Apex players, that already complain about teammates and keep requesting duos or solo for less trouble.
