Need help again:

Pls answer as you like, for me really short answers are totally fine, an Explanation would be great!
i am trying to make this as easy to read as possible, to make it easier for you

First: General Information about my account:

My top Champion Roaster:
(# = duped)

4* 4/5 # iceman
4* 5/5# Medusa
4* 3/5 Symbiont supreme
5* 3/5 The Hood
5* 2/5 Morningstar
4* 4/5 The Thing
4* 4/5#Sabretooth
4* 4/5#Doctor Octopus

I have finished act 4 once, currently working on finishing 4.3 and 4.4
I have finished Event Quest on master difficulty.


I have 5.5k 5 star shards
i get 1000k 4 star shards per 3 days.

Now the questions

1. With that roaster, when i have finished act 4 100%, should i
--> A: Level up more of my 4 stars to rank 5
--> B: Level up MS or The Hood to rank 4
--> C: Wait and safe ressources like t4 b.Cat and t4 class cat. for an other 5 star to get to R3? Maybe R4?




2. With that roaster, should i
--> A: Go for 100 procent chapter by chapter through act 5
--> B: Go for uncollected asap?



3. With that roaster, and not a single sigstone on my account, who would you use a 4* generic Gem on:
(Some personal ideas here, pls add youre own ideas )
--> A: AEgon
--> B: Void
--> C: Darkhawk
--> Add youre ideas!

I dont have any of These Champions named! But i definitly have to much time....
Thx for everybody repsonding
