What? A quick way to move all of your troops and gear into your factions fief with one click (maybe a check box). When you leave the fief or when you uncheck the box, all the troops and gear that you moved into the fief will be moved back onto your person.
If some of the gear/troops were used, only move the remaining troops and gear back.
While garrisoned, you (not the fief) must still pay upkeep for your troops.
If the fief is besieged or raided, then your troops and gear are added to the fief army and supply.
In the fief info window it should have Population, Army, and Garrisoned to show how many troops are currently garrisoned in that fief.
Why? If you're in the same faction as the fief owner, you should be able to quickly reinforce the fief while you are within it, while maintaining control of your troops and gear. Otherwise, you will have to wait for the fief owner to log on and transfer your troops and gear back to you.
Thoughts?
