Been a long time since I played Armored Princess, so I started again at Normal difficulty. No complaints though. The game never gets boring.
I'm playing as a Mage as it has been my most favorite class since KB:TL.
I like the changes in some units. Orc Trackers are nice. Specially at low levels since they have nice health and can spawn units, as Zhuangzi said. Blood Shaman would be nice in an all-orc army. Have to try it sometime at higher levels. Engineer would be very nice for anyone who likes droids. Rune Mages make up their lack of damage with summon and healing / revive.
I'll post more when I get to higher levels.
