Best setup for Acro-Multiplayer

[Truper]

I think you have a number of issues here. Taking order and luck is less than optimal, as order supresses luck. You might try taking order 3, misfortune 2, thereby increasing your income, and freeing up 120 design points you can spend elsewhere.

Why heat? You lose income, and it doesn't seem like you're desperate for the points.

The watchtower is also suspect to my mind, since many Arco troops are resource-intensive.

Arco is a great nation to take a combat pretender with, since the priestesses can heal afflictions. That Great Sage is not someone you want to use in combat.

I'm also unclear on the rationale for taking earth, as your Mystics cover the elemental magics. Nature might make more sense, even though the priestesses have it, they only have it at level 1.
