Thanks!
Yep that is how it works right now. However, I have no idea what it would look like after some intense testing. When I did playtest them, they were insanely good simply dealing 2 hits every time as defender in the later rounds - and it balanced out as attacker. It was almost impossible to take out a well-defended monastery because you had to commit so many warriors to do it. That said, I played with pretty non-aggressive factions, and I think their crippling beginning should balance out their later power. It was also before I added some of the newer mechanics (like Wrath of Jaddeth), but you'll still have monks to give a little extra attack/defense. Luckily the Wrath of Jaddeth scales, so though it can be crippling at the end, it's nothing to worry about in the beginning.
They would also struggle playing in a game with a very crowded board. So if I feel like continuing to develop them more after the jam's over, they're likely to get some changes - maybe including something that can raise/lower the Jaddeth track.
