...convert your whole kingdom to the next tier one building at a time or all once (having only level ones) ? Appreciate the feed back guys.
For troop buildings i did everything lvl one, then lvl two, and finally lvl 3, worked pretty well! Didnt take a lot time! For spies i saved for a lvl 3 then converted immediately to lvl 3...as i said, worked for me, it may not for others!
get a volley and go directly to tier 2 and upgrade guilds to level three, then get to MPB and buy lands one at a time until 21. finally upgrade to tier 3 att. GL
