Hovering over a model and seeing their movement range would be really helpful. Don't forget to implement it on allies as well!
I would personally like a "take a short wait" option as well. Sometimes you want to have one unit activate before another, but don't want that other unit to be waiting for a full turn. A 40% wait could add some strategy to the game.
If you equip a Mercenary with a Sharp Sword then change their job to Archer or probably Guardian you lose the Sharp Sword. It still shows up in the # purchased count in the store, but you can't equip it on anybody, even if you convert your Archer/Guardian back into a Mercenary. It's simply lost to the winds. If you buy a second Sharp Sword you can equip that normally, but the first is still gone.
