Sorry for taking so long to reply IRL stuff has kept us busy.
Basically, You guys can only assign Meothw to 2 Actions in total (The boss actions count separately, but you must take at least one per turn), so yeah, you cant pick actions in every category, and WaJ and Carol can only be assgined to one each, thought they can be assigned to an action where Meowth is assigned to, to include their bonuses. They can be assgined to a boss action our lovable talking pokemon is assigned to support him.
Carol and WaJ get 2 personals actions each, while Meowth doesnt cause...well what he is doing is basically counts as his personal actions.
Unfortunately this plans arent viable, gonna need you guys to edit them.
Sorry for the toruble and how late we were able to respond.
