When do you stop ranking up 4 stars?
i recently pulled a bunch of god tier 4 stars (havok, duped imiw, thing, namor) but i feel like it would start to be a waste if i continue ranking up 4 stars. Does it depend on what 5 stars you have, how many 5 stars, what content you are on, your prestige, your total base hero rating, how much you do arena, or does it depend on all of them equally, or something? is there like a milestone for when you should stop ranking up 4 stars? I super confused cos if i had four stars like namor and thing before i wouldnt be hesitant to rank them up but now i'm up to act 6 i cant use four stars anymore, and i cant get kills in aw defense because my entire defence team are four stars apart from 6 star ronin (i have no other decent def champs, so i thought i may as well put in ronin cos im not using him in anything else), but my 5 stars right now are super shabby, my only good 5 stars are blade, sunspot (whom are r4), gwenpool, ronin, (r3), vison aarkus and mysterio (r2). Everything else is absolute meme tier.
