Thoughts on Building levels 23
Building levels 23 do not require food to upgrade, however the cost of the other resources is huge meaning at least initially, only the biggest spenders will achieve it.
The Headquarters 23 requires a Blueprint item only available via an in-game purchase. That means if you want to upgrade to level 23 then you’ll need to purchase at least one pack to do so, which could prevent casual players from upgrading
The introduction of the Research scouting is incredibly useful. It allows you to get an overview of all the research your opponent has completed which can tell a defender approximately the strength of an incoming rally leader, and help a rally leader decider whether a target is worth hitting or not
Accuracy and Armor Piercing stats are introduced into the Training Ground and Bank buildings respectively, this is huge for Attackers and now means that for players who hit bases alot, using an all Bank set up could be optimum to maximize Armor Piercing which is the most essential stat when hitting a large troop count.
The increase in Deployment size from the Headquarters will help players to fill rallies especially with the large increase in Rally capacity in recent weeks.
