At the start of the next month it was announced that PerkZ would be rejoining Gamers2, who had retained their Challenger Series spot for the EUCS Summer Season. In October, Gamers2 rebranded themselves to G2 Esports.
G2 Esports quickly rose to prominence and recognition in the LCS, consistently tied for first place after each week, sometimes with H2k and sometimes also with Vitality, until the end of the split when they held first place with sole possession. With a quarterfinal bye, the playoffs also saw them strong, as they defeated both Fnatic and Origen 3-1 to win the season and secure an invitation to the Mid-Season Invitational.
Going into MSI, G2 Esports were seen as a favorite not to win, but to come in second place to the Korean representatives SK Telecom T1. However, the team lost their first four games of the round robin and ultimately finished in fifth place, ahead of only SuperMassive eSports, and out of playoff contention - importantly, this placement meant that Europe would forfeit their Pool 1 seed at Worlds. In a statement published partway through the second day of play, G2 stated that their players had taken vacation time after a "rigorous Spring Split." AD carry Emperor later stated that there had been an internal conflict within the team one day prior to the start of the event.
