I feel like the recruit button shouldn't take up half the icon for selecting the hero, and it shouldn't default to accept when trying to recruit a hero either. Both of these add up to make accidentally recruiting a hero an easy occurrence. I think just removing that small bar on the icon is an easy fix to the problem, as you can still leave the UI for recruiting a hero once you've selected it. I accidentally recruited a hero earlier this morning, and I'd rather not have other new players go through the process to grind up steel just to waste it by recruiting a hero they didn't want to. Its not a good feeling lol
