I've always felt that people give too much credit to using poor genetics as an excuse. Everyone obviously has genetics gifts, and uh.. non-gifts (lol) in regard to certain sports, in this case, we're discussing building a physique that fits into certain preconceived proportions.
Each person has their own 'road to travel' in the gym, in that they have to address different issues than other trainers might. As such, I like to think that as long as you're not discussing the highest levels of the sport (IFBB Pros), that everything sort of evens out in regard to strengths and weaknesses. I always felt that my hips weren't naturally narrow compared to others I knew, but in my efforts to offset it by improving my upper body and quad sweeps, I ended up bigger overall. Perhaps someone with a more pronounced V-taper from the get go may not develop the same level of thickness that I had.
I understand that most people want to build an "imposing" frame, but whether that means impressive from a competitive bodybuilding sense, or just filling out a XXL t-shirt are two different things. You'd be surprised how many trainees whined about their poor V-Tapers until they finally bit the bullet, dieted down, and realized that they actually had a much narrower waist than they suspected!
