Obito destroyed Tobirama and Hashirama as well, several times. it's only when Minato attacked that Obito gained the power to permanently damage Edo Tensei and so got hurt. I always see people using this as some anti-minato excuse whereas prior to Minato's attack, there was no reason to believe Edo Tensei couldn't regenerate.

He also made numerous major impacts like helping Guy's attacks land, saving the entire Alliance twice, and defeating Obito with a Rasengan.
