Fails/ mistakes thread

We’ve all had our fair share of fails and mistakes in mcoc. What are some of your worst decisions?
For me, it is taking 5 star iron fist to rank 2 when I needed t4 basics, using an awakening gem on drax, and not reading a node in the masochism chapter of act 5 on some fights that added 10% buffet.

I really need t4 class cc so I really regret taking my 4* loki and modok (mostly loki) to rank 4.
They were some of my first 4* champions.
Also, I really regret spending units on grand master crystals (when I became uncollected I spent all my units on the feautured grand master crystals)
