Do we need an OP Hero in the MCU

Rating: 4/10 (9 March 2019)

When they introduced Thor, Hulk, Scarlet Witch they lowered their powers so they wouldn't be OP and one punch every bad guy.
Now we are introduced to Captain Marvel the Super man of the MCU (if you have seen Justice League you know what I mean), and people will start to ask do we need The Avengers if Captain Marvel is so OP.
