going back to the boring bosses is not cool either, but fun & engaging doesn't mean it has to be harder..., INSTEAD bring fresh ideas for mechanics & grafix displays (like the tank buster in Ex1, think its called mountain buster, its not hard to stack in a line and move asap left / mid / right, depending on the boses postion, but its fun / engaging, or the big sword attack from Sudano, just add sime more flair to it etc.). so the casuals are not pushed to hard and we feel still feel engaged
