Well, without repeat battles, I could level 4 fodders at a time. With repeat battles, I can level 3 fodders at a time because I need to use my own farmer. I didn't realize repeat battles wouldn't be a QoL but a tradeoff but hey if that floats your boat, I can't really complain.
which, again, isn't really YOU being efficient if you're relying on others heroes to do the work for you
I don't understand your point here. So do you refuse to use supports in this game just because it is not YOU playing it but other heroes? Even for mundane things like farming?
At least make some sense if you want to be contrarian. Is it too difficult to ask for? (I apologize if you have an impairment which does indeed make it too difficult for you.)
