SpringSoldier said: @aa25 For players who maxed out their 2* and 3* need ISO to max their 4*, that's not a very good option anymore.
2* farming is one of the best things you can do if you play the long game.
Farming 2*s is ISO-neutral compared to selling the covers, but you get CP, HP and 3* covers in return.
