2 SP rolls: 2 useless bronze units
5 Basic rolls: 3 silvers
I trully hate getting bronze units on rolls... i mean, irons are needed to CC, silvers are needed to CC and AW (which need to be CC'd so another point for the irons) and they are a core part of the game, very usefull tier all and all. Obviously golds+ are always good
Let me stress the words "ON ROLLS" because bronze are one of the best fooder but when rolled they are lv1 so you would be wasting gold when combining and lets be honest, when was the last time you used a bronze mage or a bronze heavy? the only bronzes i have are 3 mincost bronze soldiers for early rushes scenarios but usually my silvers can handle them
