What should I do now?

To preface, I've hit a point in my progression where I feel kind of lost on what to do next on my account. I've reached valiant and have a pretty decent collection of a roster with a rank 4 and a handful of rank 3s. For the first time I feel like I've reached an "endgame" status or at least a point where I'm starting to aspire towards endgame content but I don't really know where to go first.
I've fully explored act 8 and what's available of act 9, and I've done at least one path of Epoch of Pain (Path 1). The problem is I've saved up a good batch of units (4k+) and I'm lost between whether to attempt Necropolis, explore epoch of pain, or try the ordeal, or even just do nothing and save up for July 4th. I'm not really sure of what I should do or even what I can do.
Some suggestions would be helpful! Here's my roster for reference:

Also as a general question, should I bring a reverse control immune champ like Jack for DThanos? I'm not really great with reverse controls.
And yeah, shuri really helps even at r2 she can take tough fights like domino sassy km
