Enticement for farming

I am getting tired of auto farming S1 pro 22 and 23 due to the high xp/flag rates except when atlantis is risen. Much to my dismay that one cant get atlantis coins for farming S2 unless it is risen. Idea of the rare reward of a token A coin would not break the game and could encourage farming of S2 which had much lower Xp/flag than s1.

Ps gold troop token as reward would not unbalance the game either. I could be a reward for farming S2 also instead for silver troops
