As a player that has been playing this game (and WoWS) on and off with massive breaks of months in between, it would be nice if there was some kind of platoon search function in game. Every time I come back, all my old buddies have quit and there is no one to play with. The game is much more fun in a platoon where everyone can suffer together. There was tank companies in the past so a building a platoon search option off that doesn't seem too hard.
Just my two cents.
