As per title, what is a good build order for the Celts on Age of Empires Online?
Finally found a guide, from http://forums.ageofempiresonline.com/forums/permalink/262389/262389/ShowThread.aspx#262389:
To quickly train a new units you may also use shortcuts. Double-click on a barrack and shift+(number6), archery range(7), and so on. So when you want to get a new swordsman you just need to press "6" and then "S" ("A"-1st unit[spearman]; "S"-2nd unit[swordsman];"D"-3rd unit[woad Raiders]; "F"-4th unit[champion]).
