A friend had finished painting up his goblin warband so we got together for a game at my place. Free the Princess was rolled up. I won the dice off for choosing attacker or defender, so I chose to defend with my undead.
He had two battle groups that were each a Wiz and two spitters, plus a winggit. And also a melee group.
Some early group shooting from those two ranged groups were quite alarming (my wraith had barely landed in a building roof before he was blasted off), but once I’d closed on his winggit and held him back, my Barrow Wight and werewolf were able to clean up.
Yeah I’ve struggled as attacker in most of these style scenarios. I’ve lost the stores and princess and beacon as attacker, but have won beacon once as attacker against a new player.
The 1.1 errata update made the asymmetric battles more balanced by making the Free the Prisoner/Light the Beacon/Fire the Stores actions short instead of long. A small change but has made a big difference in my games.
