4* IMIW worth taking to 5/50?
I’ve got the t4cc and t4b cats to rank up a tech champion. I can rank up IMIW Sig 22, 4* SL Sig 43, or 4* Yondu Sig 41.
I also have a 5* Ultron unduped I can take to R2, and save my t4cc to take him to R3.
My alliance isn’t in a high tier, so a 5/50 IMIW would be a great defender. I’m just not sure if it’s worth putting the resources in to a 4* just for war defense. Thoughts?
