While I am fairly critical of the grouping system because of the workload added, I appreciate the idea of using heroes to lead groups. So my main beef with the system is workload, before every battle. I typically set up standard infantry, archer, and cavalry groups in every battle. With the same heroes every time. I know if they are injured they can't lead. Then in groups 5-8 I make very small groups lead by other heroes and call those groups to myself as a bodyguard. This is the same for every open field battle I fight. The main workload issue is that this setup does not stay fixed from battle to battle and particularly after you do a siege. It is tedious to keep doing the same setup over and over when the computer should be remembering it. Now in sieges I would want the workload thing to be minimized as well and my setup remembered. In sieges though it seems like no matter what setup I do, when the battle starts, it is gone. I might make groups 5-8 but they have disappeared once the battle starts.
