Rank up advice for burnt out player

I'm all caught up story content wise and am now just waiting on 8.4, LoL, Aol and necro just seem way to much for me so i often just find myself doing a path of act 6 and 7 every day or two, war and the side quest, the only carina challenges i can see myself doing right now are the RoL ones so thats that but im thinking i can rekindle my interest if i rank up some cool good champs, any suggestions on what i could do. down below are all my 6* r1's. I can identify the champs that are are immediate r4's and i would love to myself. But I have most at 5/65 and not enough ISO and gold to rank those that i dont have as a 5*. So they just stay unlevelled

How are you doing in solo shards for the new gold and iso crystals? They soon provide a lot of gold when you pop 1mil+

For me, from your r1s, I’d definitely be thinking about tigra, and then shuri, Titania and Shang if you don’t have them at 7*

I find the MagicApollo tier list useful as they average the ratings of some reliable sources, it’s guided a lot of my rank ups.
