Kim "Doinb" Tae-Sang from LNG recently went online on a stream. During the talk, he spoke about something unexpected. According to Doinb's words, LPL players are not allowed to stream other games, apart from LoL. He also said that for doing so the players might get penalries and it also refers to mid-seasonal period.
Despite this, other League of Legends regions do not use this sort of rules and conditions, and players are allowed to stream any other game they'd like to.
Doinb's LNG Esports currently is placed 7th in the ongoing League of Legends Summer Split. They had 3 wins and 2 losses. Their latest match was against 3rd place Top Esports, where they took the match in a 2:0 manner.
