This is one of the most minor upgrades I’ve ever suggested…
The Castle Guard currently has 8 waves. But for a maxed out Castle Gate 14 waves are played. So it just repeats the first 6.
I’m requesting an upgrade that unlocks the an additional 6 as they become appropriate according to the Castle Gate / Castle Guard stats.
The reason is: if I had the choice my 14th wave would be nothing like my 6th wave.
Further with the Blacksmith Shop and infinite possible weaponry upgrades you need to allow improvements in the defenses to keep up.
This is a simple improvement that should have already existed.
