Do you think 4* champions are still relevant?
I have 15 5* (Only 4-5 usefull) and bunch of 4*s and currently i only focus on my 5* champions but i need more champion for aw and aq for diversty. Should i rank 5 my 4* champions or just wait to open more 5*s? I'm asking this because it's still relatively hard for me to get t4cc and farm gold.
