On October 31st 2014, Gambit Gaming announced the departure from Kubon as their top laner.
On November 12th 2014, Kubon rejoined Reason Gaming together with Xayoo.
With Reason Gaming, Kubon competed in the Spring Expansion Tournament, and qualified for the Offline Stage of the tournament after beating both SK Gaming Prime and Different Dimension. In the Offline Stage, they lost their first matchup against GIANTS! Gaming, but they still had a chance to qualify for the LCS. The team went on to beat n!faculty in Round 1 of the Loser's Bracket, but then lost to GIANTS! Gaming in the Loser's Bracket Final, meaning they will be playing in the upcoming Challenger Spring Season.
Kubon competed with Reason Gaming in the 2015 EUCS Spring Season after qualifying via the Expansion Tournament. The team finished 5th in the split; however, the fourth-place Team Dignitas EU had two underage players on their roster and so gave up their spot in the playoffs, allowing Reason to take it from them and advance. The team finished in fourth place, out of reach of the Promotion Tournament, but successfully qualified for the EUCS Summer Season. However, prior to the start of that season, the roster departed the organization.
