There's a huge amount of turnover in the Chinese scene. By far, the surviving Chinese rosters from last year are only EDG, FPX, NTER, and ASE (you can count NOP as well.) EDG and FPX has the stability for almost over a year now and heads above the rest in terms of experience (EDG being the only Chinese team to attend two international LANs.)
Give it some time, the progress will start as the scene stabilizes.
