The planar sickness idea is basically a paratrooper combat penalty transplanted from another game. It just seems to make sense to me to give teleported troops some kind of fatigue penalty.

A turn represents an entire month. I'm not sure why stepping through a gateway would make you more tired than a month long march into enemy territory.

Arranging things so that your mage fights several battles in a turn may be tricky, even with potentially 11 battle rounds a turn.

You can expect to see at least two battles a turn on average for major armies. More if there are multiple opponents all attacking you at once.
