Add another mutation slot via milk molars or the ranger station shop and allow the quick swap between mutation builds. It takes way too long to swap when you are in combat. leaving you vulnerable to attacks. Grounded 1 you were able to upgrade via milk molars to five mutations active and were able to have the radial wheel to switch between them during combat which is essential. I know others have asked for this in the Grounded 2 discord, so many people are hoping to have this helpful option back into the game.
