Why is Indar the superior continent?

The Crown.

This might be the best feature about this game. It's a mountaintop fortress with near perfect line of fire on every approach route. I love defending it. You can hold it with only infantry against a superior force even while all your other territories are falling.
Often you have the 2 hostile factions attacking, each from their side.

I do agree that because of the position of their warp gate (and perhaps the terrain) TR has a significant advantage in terms of holding territories.
