Hey, thanks a lot for the detailed feedback!
I'd say you captured the essential design choices we tried to convey! Mainly, the fact that skills dont synergise is supposed to represent the clumsyness of the boss, who's more used to crush heroes mindlessly than growing veggies!
In a design stand point it's a bit frustrating, but when you get the hang of using skills while managing you positionning it gets interesting (imo).
