"Rookie-2009"

Turns out Shakhti, like Kyrre, placed a level 7 on the second week

Yes, I confirm, I ran out of money because of building dragons

Guys, what's the point of placing dragons on the second [week] if you can't afford to buy them out? :) From my noob experience, dragons are rarely placed at all, especially for Dungeon. Place troops with affordability in mind!
The same goes for buildings on the first [week].
One example is the notorious "horses in Castle", only to have no money to buy them afterwards. Often "horses in Citadel", and sometimes even in Fort, with a full buyout on 121 — this leads to faster development in the second week.
As a rule, what usually rolls is not the quantity of native troops, but hero leveling, map scouting, earlier finding and capturing of important objects — banks, high-level pickups, beehives, cans, sunken ships...
These are just thoughts out loud, not direct instructions for action :)
