Wait you're taking champs up to R5 and don't have act 4 explored yet?
I have act 1-3 explored and act 5.act 4 was so long for me so i left if out but i need to explore it now for t2 alphas
I have both 5/65 and 2/35 rank ups and my advice is to only rank up champs who will help you conquer game content.
