This is how I feel whenever I hear a complaint about the game or a wave that has only been out a couple of months.
And the knight is underpowered
Clearly the knight needs a title to overcome its initial overcosting.
Perhaps it's time for Armada 2.0, to sort out the issues that have been there since the core set.
We play with a set of house rules that make the knight more balanced. Now it can jump to ANY space within 3 spaces of its starting position, unless it has to jump over a rook to get there. Also, it takes two pawns working together to kill a knight.
Also, the King can perform any move that any of its surviving pieces can make.
