Battleground bank resources conservation
I keep seeing that battlegrounds take up 5% resources wort units from us as their interest for loan.Does that mean if we keep playing battlegrounds with our current troops and do not train more troops also we keep sending our reward recieved from battlegrounds tournaments to lets say our fortress and avoid them being engaged in pvp battle.then we would eventually run out of units to play battlegrounds??? Is that 5% interest of battleground bank means we would never get 100% resources back from battlegrounds???please help
