So I have 3 casters in my campaign so far. I'm on the second map. I have Darwella, but she's is ALWAYS put to the front lines automatically in fights, which means that if I fight a battle with a group that attacks first, she'll no matter what because thats who they go for.
If you're not going to allow us to place our units, then make it so casters are far away from the frontlines as possible. It's common sense.
Also i've had to reload my game twice because either Relias' army gets stuck in the water when embarking a boat and he can't get out, or I can't land on an island (i've pressed the turn button multiple times to make sure I had a fresh move each time after furiously clicking for 10 minutes).
The boat mechanics are really clunky.
