Honestly, I would just skip act 5 exploration since the rewards aren't worth the effort to explore anymore, and go for act 6 completion. As for your rank up advice, I would rank up your hyperion because his damage is really good, and great damage is sometimes more useful than good utility. Especially in Act 6 where the health pools are so small compared to act 7. I would hold off tanking Joe until you have awakened him, it is really helpful not having to work to get your hand back after every special. Diablo is very suicide friendly, but I assume you don't run suicides. I haven't played with BWCV myself, but others enjoy her. Ægon won't really help you in act 6 except against the grandmaster. Shang chi is a great option because of his damage and utility. I personally enjoy having cap marvel movie paired with Nick fury. I wouldn't rank your 6* Cap IW since the 5* will do just as good damage wise and your 5* actually has utility. My last input is stryfe. The man is a beast, and I honestly wish I had mine as a 6*. With your current roster, you should be able to beat act 6, and if you hone your skills more, you shouldn't have too much difficulty with act 7.1. 7.2 and 7.3 aren't much harder than 7.1 either.Thank you for joining my Ted talk.
Might In suggesties you rank up Venom and use him on the variants? These will give you a lot of rank up Materials and a wider roster via 5 and 6 Star shards. This Will give you a better chance of having a Great counter. And you can rank up multiple of you obtions to atleast rank 4. Venom initially was 1 of my faves…would not mind maxing him …what Variants U suggest I should initially try?
Rank up your Guardian
