i'm not even an obito fan.but truth to be told madara was trash from the moment he was introduced,he was heavily protected by plot:
-onooki never tries jinton when madara is in susanoo(the moment when he can't absorb it).
-the kages uses lighting to paralyse him,yet magically he's out,power of plot.
-alliance get a power-up from naruto to fight him,they get nerfed the fuk out,and offpaneled,just so he can survive(for god's sake hinata of all people slapped the juubi's hand to a mountain by one juuken,what would hiashi or kakashi or anyone else do?),and magically uchihas are immune to mind control(something he shared with obito).
-gets cut in half yet nobody is there to seal him.
-hashirama gets nerfed and deprived from 1k hands so he can survive.and still when he beats him,hashi gets an off panel plot black rod in the back to
-gets revived blind,everybody around him forget their powers(naruto and bijuus don't use TBB on him,sasuke no susanoo..so he can get handed bunch of power-ups)not to mention eyeless susanoo and plug and play eye and hand.
i still want to write more why madara is shielded by plot but everytime i write more i get more annoyed by the lengths kishi can go so he can preserve madara's life,for the job of the final villain something that he didn't desereve as character.
