Option to automatically deploy all armies to the single available territory
If I have only one territory then there is no point of placing armies since this is the only place where I can deploy them.
Instead using this option it would automatically deploy all to the only available territory and skip to the Attack/Transfer phase.

There is not much strategy to think when you have only one territory, so the risk is really small.
When your only territory is surrounded by bonuses of your teammates than the only thing you can do is to send armies to your neighbors over and over again. -

How much time does this really save? Two clicks? I would think it would result in more confusion because it skips a phase (might hit commit before you have thought everything through).
