It's an estoc war. 1 hour long with a knockout system. You are assigned to a clan with a group of other people and have to knock out the opposing team to gain a higher plunder score at the end of the war to win.
Would it be more efficient for me to change all my highland SOS to level one volaries before upgrading any to level two, to change each SOS to a lvl 2 volary before upgrading any to lvl 3, or changing each from an SOS to a lvl 3 volary one at a time?
