monarch sort of pigeonholes this game into never having well balanced low placement units. you cant really afford to print a unit like gogeta without monarch gogeta being objectively the best unit in the game, and other low placement units would be forced into being either terrible without monarch or broken with monarch.
monarch damage increase is 300%, or a 4x increase. this means it's good for any unit 4 placements or below, and actively detrimental to the total dps of 5 placements or higher, making high placement units objectively not very good.
this shows in the game's tower design already, 99% of towers are 3 placements because it's really the only placement number where monarchs can be "balanced" relative to their rarity.
the solution to this issue would be monarch damage scaling. this would nerf prominent issues like monarch gogeta (without making regular gogeta worse) and buff units like ha chae in who struggle in the meta because of their placement numbers.
SCALING:
2 placement: 200% (3x damage)
3 placement: 300% (4x damage) (the standard increase already)
4 placement: 400% (5x damage)
5 placement: 500% (6x damage)
etc.
