The devs should really consider a “Sell” option for battle Incubators. This would encourage more battling and provide a bit of a gamble as well. (What am I letting go vs what might I get?) It also provides another option to gain coins or cash. Could make it somewhat random, min x amount of coins to a Max of x amount in cash possible. There is just too much room to work with in this idea not to do it. Make it happen devs!
