Your statement doesn't really make sense. "make the pants wider through the leg" and "they have no taper". If you widen the legs they will turn more into sausage tube leg pants. If you tapen them they will get tighter. Lay them flat on the ground. There is a slight amount of taper. But if its taper you want go for the fatigues.
But at the end of the day almost everyone has a different idea about how the perfect jacket/pant should fit. We just try to make things that look and fit well on the majority of people. We use our team as our guide. They seem to like it and make it look good.
Thank you for the input though.
