How would you make the most OP archer build?

Personally I started with

• keen-sighted: +20% accuracy
• overwhelm tactics: adjacent +20% crit chance
• barbarian culture: the only early ranged unit they have is T2, the fury, making it better than the T1 from ‘high’
• fabled hunters: ranged +1 rank and start with extra ranged unit
• runesmiths: cheaper unit enchantments
• tome of enchantment
• champion: for the 10% extra gold income

Also, do you think anything will change in this build with the Dragon Dawn DLC?
