What do the game devs consider the best units?

[Sandsai]

There is no such thing as the best unit. Some are far more valuable for certain battles or for certain classes. But really, the beauty of this game is that no matter what units you get in the shops, you can still make it work and do just fine. On a side note, I would say that any female units along with Anga's Ruby are a bit overpowered imo, + 3 morale is way too much, not including +3 to damage. So if you are looking for an overpowered army, go with a female army with Anga's Ruby.
