We need new gamemodes
For the past few seasons, the game modes have stayed the same, and it feels like the game has gotten a bit stagnant. They should bring back popular modes like Three Strikes, Solos, Arenas, and 1v1s, and make them permanent modes.
Also, the problem with the current ranked mode is that the player base is divided on how it should be played. Some people think ranked should be combat-heavy like pubs, while others believe placement should be more rewarding. The thing is, since there is only one ranked mode, it's impossible to satisfy everyone with how it currently plays out.
They should introduce alternative modes like Wildcard Ranked or Three Strikes Ranked, even if just for a limited time. Sure, there are ranked ladders, but they don't really affect how fun the game is. Having multiple modes would allow different types of players to grind the ranked modes they actually enjoy.
