A reliable twitter account for Korean news has suggested that Lustboy has left and will be replaced by Gunza.
Long time support Ham 'Lustboy' Jang-sik is said to have taken his leave of CJ Entus Blaze, likely not keeping up with the top tier support talent in Korea such as Mata, Gorilla, Heart, and a bit less so recently, Madlife. Lustboy has been with the team since November 2011 and therefore has nearly hit 3 years with the team.
If the alleged changes go through, he will be replaced with Jung 'Gunza' Gun-hee. Gunza currently occupies a substitute spot on Samsung Galaxy Ozone, but most recently was on the full time team of Quantic, who failed to qualify for the North American LCS.
Though the evidence is not perfectly clear, it is likely we will see the former Lustboy and Emperor bot lane duo parting ways in hopes to strengthen the team before the next OGN season.
[Rumor] Lustboy leaves CJ Blaze, Gunza replaces.
