Well actually I think they should update/upgrade it so that guild leaders & possibly counselors should be able to dismiss guild army units. This way they won't have to kick people out of the guild just to remove units from the guild army. As this is the usual F2P time game format, not everyone will sign in all the time and may take long stretches of time off.
I removed XxxEdEnxxX and Hayden from our guild because they had poor equipment and low level units and the were inactive so I could not ask them to upgrade their Army Units and give them better Gear.
If I had been able to upgrade their Units and Give them Armor, Weapons, and Potions, I wouldn't have had to remove them.
It would also make sense to automatically remove someone from being Guild Leader, if they were inactive for months and months. Well if there is more than one person in the Guild.
