You should definetly do completion of acts 6.3,6.4 and 7.1You'll also probably be able to explore 7.1
Complete 6.3, 6.4, and 7.1. They should be quite simple for you. You should also be able to 100% v4, 5, and 6. I suggest doing completion of v2 also. This is all based off of what I’ve done with my roster when comparing it to yours. A lot of my top champs are similar to yours and you actually have a lot more than I do.
You can do everything with that roster. Im really surprised your not at least done with Act 6. And you can do every single variant itemless with that amount of 5/65s. And awaken that CAIW and Rank him up
I'd focus on apoc,sentinel,void,stealthy,bwcv for variants.
Give Ghost some sigs if you haven't already
Yes, personally save variant 1 for last but you have a roster to beat the game
You really need to R2 some of your good 6 stars
