How would you feel if the only way to play as a cast character in PQs is through the soul switch mechanic?

Just to preface, I really doubt this will be the case but I'm curious.

Only bringing this up because the more I think about the mechanic, the less it makes sense. What's the point of creating a character if you're just going to transform into Trunks? Why wouldn't I just choose Trunks? I guess because of the changing moveset and the buffs? Plus the only time we see playable cast characters (Vegeta, Piccolo, Krillin etc) in the first trailer is through this mechanic.

But at the same time, it doesn't look like you can transform while Soul Switched and I doubt we're getting a game where you can only play as base form Goku. Unless transformed Soul switches are different characters.

Either way, how would you feel if that was the case?
