Is this a good build? 10 level 3 subterrainian factories 1 level 4 guild, 3 level 3 guilds 5 level 3 summoning circles 2 level 3 forges
Plan ahead... Main goal of Pre-LC is simply growth... Or social aspect, so you would be focusing on plunder, so defensive buildings... Assuming your goal was growth.. At LC and post LC, people usually plan a build for later and start to modify it, so in actuality, once you have LC'd, building Tier 4 and building on Highlands is all personal choice on the style you choose to play.
Upgrade everything to it's highest level. Get rid of the forges and build something stronger. And I assume you plan to upgrade everything to t4 later.
