Rank ups only for challenges?
I would like to hear your opinions on ranking up champs you wouldn't normally use just to make a specific challenge easier?
From the carina challenges 1-3 i have done all except the Carina Challengers Abyss one, will do that soon. I use the champs for that all the time, so i would have maxed them out anyway (Void R5 ascend, Falcon R5 ascend, 7*R2 Guilly 2099, 7*R2 Diablo, R4 Shang-Chi he will probably stay at R4)
Now when i look to the next challenges there are champs who i don't use very often, for example Karate Mikes with the Avengers.
Did you all rank/sig/ascend your ant-mans, black widows, tigras, jabari panthers, mojos, zemos, etc for the challenges?
R5 seems a bit much but R4 resources are well accessible at this point
As for me, I don't do BG really, and my roster is fine enough, finsihed every content except two paths in abyss, so it doesn't seem like wasting resources...
How did you all approach those challenges?
