No one cared that the Avengers didn't show up in Thor 2, Cap 2, or IM 3. "He's busy" is a perfectly adequate excuse that now has precedent in live action.
Except that you eventually do get a pay off when Avengers happen. If you're not going to get a pay off of this sort in tv, why even introduce him? Heck, if excuses are what we're looking at, just make it happen before Superman becomes superhero.
