it's hard for the Minotaurs to fight alone)
and the Elves, even though they only have archers, they are very strong))
as for the Dwarves and Dendroids, I don't know, I have them with me and I can defeat everyone and move around normally))
regarding the castle assault, it's not a given that the battle will be in the castle)) it rarely happens that the main army is in the castle))
P.S. for me, they are better balanced than the Dark faction.
