Does being successful count as being better than your main team?
For me , an academy team as a whole becomes successful when at least it's core gets promoted to the main team itself.
This has so far only happened with C9 , who even won a LAN trophy with the team . Mouz though they haven't had that much of a success and now fot Spirit !
Worth shouting out are Bit and Monesy from NaVi who got into different T1 teams too and left their mark ! Headtrick is part of a T1 org as well so one can argue that NaVi Junior were pretty successful too
apparently yes. gambit youngsters had their first roster in april 2019, while the only other "old" academy roster i can remember is navi junior, which had their first roster in july 2019.
i was sure that navi had their junior roster since at least 2017, but it seems like i was wrong
