Time to decrease 4* Rank up costs?
Just a thought but why is it still 5 T4B and 3 T4C to rank a 4* from R4 to R5? That's actually more than it takes to take a 5* from R2 to R3 even though a 5* R3 is better than a 4* R5. Maybe it's time with 5* and 6* so much easier to acquire for Kabam to lighten the load for the lower level players to be able to rank up those 4*.
