This is not to say that EG isn't good, the team they currently have is incredibly good, but the whole 10 man roster thing is not going to work out for them the way they intended.
The whole point of a 10 man roster is being able to scrim yourself, be able to hide strats from other teams and prevent counter-stratting as much as possible while experimenting as much as you possibly can with no limit.
EG so far has not experimented enough, they're just playing the same standard comps as everyone else, and as a result of other teams scrimming each other against the exact same comp, they already know how to play against it. In these situations EG only loses in the end because everyone else has practice against a bunch of slightly differing styles with the same comp while EG only gets practice against one.
Their main roster is good already the way it is, they don't need to waste more resources into trying to make this backup roster work if they're not going to capitalize on its main advantages.
They denied scrims from NRG ffs, if they want to be good then they need to play against the best or try to figure out a strat amongst themselves that can challenge the best and switch up the meta.
