Does counting carbs and fats matter while eating high calorie?

On a cut it definately matters as I'd feel like shit without both 25% fat and as many carbs as I can fit in while getting 25-30% fat, but when bulking and eating 3000+ calories (3500+ depending on how hard i'm hitting the gym at the time) does it really matter as long as you are hitting at least 25% fat? is there any problem with having 150+ grams of fat a day and still getting 300+ grams of carbs but just counting protein then calories in this scenario?
