But if you cannot recall your mech while in a fight, then it's broken because your group is now effectively minus one tank for the rest of the fight. Then there's the fact that it'd take basically double the effort to balance, since the class becomes 'two in one' per spec.
If I recall correctly, I do believe Jeff Kaplan said that the only reason Overwatch has D.Va is because the team fell in love with the character, otherwise she wouldn't have been implemented as she is, by far, the hardest hero to balance, and the one more prone to 'break' and bug out, due to effectively being 'two-in-one'.
