Ok, so now I have seen ONE positive person, Hannibal, telling us how much he likes this feature. Makes GE faster (because GE is all about speed for him, apparently?).
My question then is: How long will it stay such a nice feature, if you are going to have to start spending lots of dollars to be able to continue using that nice button? 64 battles, could easily run to 500-1000 diamonds.
Making units costs nothing, building up Traz needs no $$. Changing out troops ever 4-5 fights is pretty rapid, Healing an occasional main unit when it gets killed is a useful option. Healing them all is just a crazy waste.
Maybe someone will show up here, believing his army is real, and he is reducing their pain? Now that would be a good argument.
