Bpn88855

Hi,

could you please help me to decide who to r4 6* from?
Already have r4: Doom and Apoc. Was hoping to get Hercules, but no luck. So i will get rewards from EOP in 2 weeks and for Paragon will go with rank up.
I have generic awakening gem and can put into champ 200 sigs.

Have a lot champs to add to poll, but 10 is max. Aegon (i think r3 is more than enough), Wonk seems good option (just got him), Hyperion (undupped and r1 so far, have him as 5*), Omega Red (undupped and r1 so far, have him as 5*), Namor (undupped and r1 so far, have him as 5*), Scarlet witch sygil (not using much), Captain marvel (undupped), Spidey 2099 (undupped), Stryfe (not using him), Human Torch (r3 so far is fine), Diablo (nice option r4 maybe), Kitty Pride (r3 is good so far).

I am also more to NF as for next rank up.
