Sounds good, the barb will probably attack the Archer on the Copper hill. Vesta can heal in the city it will be quicker and I do think were going to need a good number of units to spawn bust quickly since we don't have horse yet.
Actually why don't we move the archer one more se to the jungle hill? The barbarian will attack across a river, and we'll have the jungle bonus. Afterwards the archer can take up spawnbusting duties while Vesta heals up.
