We do. We saw last season that we have no-one else who can dictate the tempo like Scholes, and that is down to experience. now TC and Ando are fit, they should get as much game time as possible.
I would use Scholes as we used Giggs last week, bring him on for the last 15-20mins, when everyone is a bit tired and then he can help us see the game out.
We do have to keep them involved though, at their age you cannot miss 4 or 5 games and still come back sharp. 15-20 mins every few games should be enough to keep them up to speed, but while TC and Ando are fit they must start now imo. It's the only way they will get the experience to be able to control games.
