100 reputation for elves and humans is quite achievable.
Without using exploits, yellow makes many problems.
In the advanced difficulty, the capitals have Tears of Ashi buildings, which increases the defense army. And something else.
well, with my army in the dwellings, this reinforcement is just useless.
I have left from your list: capture humans, elves + treasury, and turn in the blueprints.
and I only have 85 reputation
