Yeah, although I hope they don’t nerf them so much they’re useless.
It should take longer to charge the perk, and maybe the explosion should do a bit of self damage (pretty sure it doesn’t currently).
Maybe raise the energy requirement another point or even two?
I am really enjoying playing them. I’ve always liked the goblins and gremlins, and these are more fun than either of them ever were. I like that you don’t need to run a lot of them, compared to the lower end versions. Gives more building flexibility.
