Sentinel or Iron Man (IW)
Hey there,
I just got a 5* tech rank up gem from 3 to 4. I only have 3 good tech champs, Star Lord (already rank 4/55), Sentinel (duped, 3/45), and Iron Man IW (unduped, 3/45).
Should I go for Sentinel or IMIW? Or perhaps wait for other tech champions?
Thanks for the input.
