This is important because the League of Legends community of gamers wholly embraced this game mode over the weeks that it was active. Players took the time to become skillful and masterful in this mode which more than other game modes specifically because of its design inherently fostered team work, team spirit, and an overall atmosphere of cooperation and players working together. All of the great things we love about League of legends. By bringing back this game mode, Riot Games will most certainly be teaching players the necessary skills for other game modes but most importantly it will continue the mission and spirit of Riot Games, including cooperation and team work.
