Yatsuka Caedye and aace are not old enough to join ZETA T1 at the time. And even if they did they had Sugarzero Dep and Laz so I don't think it's going to be easy incorporating the new players. So I can't blame ZETA regarding them not picking the current riddle players.
Zeta likely won't take them back. The buyout clause has to be too much too handle π. But I expect at least one of them is going to zeta sooner or later, knowing that zeta will probably bench Yuran and by some degree, hiroronn.
