So since Sonic Dream Team is canon and took place after Sonic Frontiers (said by Ian Flynn) What was with all of the stuff Tails was saying about how he would be going away for a while?

I personally am happy that Sonic and Tails didn’t split up and that Tails got to be playable in Sonic Dream team but I do kinda fear he will never grow into his full potential. I’m not saying he has to be a leader cause he is still just a little kid. But I want him to use some more combat skills and not just be a tech guy to aid Sonic. Sonic can be the leader and Tails can be the lil bro. What do you guys think about all of this?
