Mighty Storm Tower Omega Cell 2

Several people have said they way to beat Mighty Storm Tower Omega Cell 2 is to use the following team:

​

MCU Sue, Reed, Franklin, Quasar, Hyperion

​

All gear 20

​

I've tried this repeatedly and get wiped every time. My characters are all level 105, 1 to 3 diamonds except Quasar who is 7R.

​

The people who sat this team is a winner won't say what level their characters are. Since 105 is not doing it I'm thinking it must be 110. But before I think about investing the mats to level them to 110, I need to know for sure.

​

So for those who used this team successfully, what of my team is lacking? Level? Are they purple 5? What?

​

Please advise!
