Guys Just want to ask

I tried upgrading chromia as I got her as reward but I noticed that upgrading is hard now.

When I upgraded Flamewar and Slipstream 2 FW 4 SL it was so fast using R2's

I can remember when they are level 20 8 R2 will shoot them 5 levels now Chromia is only level 22 but level up is on 2 per 8 R2's
