So let's divide each of the sides into strengths and weaknesses.
Aurvandil:
Better single realm army
From what I hear, better general
on defense
only uses gold for military
Doesn't have far to refit
winning streak
The Theocracies+Terran
Gold lots of gold
Bigger total army
can invade from pretty much anywhere
more total nobles
terran can harass paisly and paisland while the other fight down south
what did i miss?
Harass Paisly and Paisland? You mean, outright take it away from Aurvandil, right?
