It really depends on your kid, My little girl has never been into anything but superheroes but she is also real careful with everything she owns (still have accessories and weapons for everything) but she got JLU figs @ 4 then we did like you and went to squads but from 7 she has been playing with MU and no problems.

She keeps everything in tubs so they are still treated like the toys they are and other than the odd leg popping off (more an issue with certain bucks) she has been fine
