TTK is fantastic. This and banner revive makes the game much more squad strategic. Play the map, cover, and other teams.. don't just charge at the first enemy you see because you want bigger suicide kill numbers.
Only thing the game needs is a consistent 1-2M simultaneous players, to support a ranked queue with skill based matchmaking.
Ohh, and a working lobby. An ingame way to invite people without adding them to friends. A setting to ignore origin notifications while in game (especially invites). An audio mute hotkey. Hud ping info, Mic volume capture gain.
Then, a couple hundred million in profits to support adding death cams, spectator replays, in-game cheat suspicion reporting, spectator mode, and an esports league - to make a billion or two.
