You're just trying to rub your ego. I can dominate PvP in a lot of other FPS games (that I actually like), while using the most underwhelming weapons. Doesn't mean that those weapons aren't gimped/underpowered. It's not about subjective opinion, it's about everyone having an equal chance of doing well, regardless of what type of weapon they choose to equip. A perfect balance is impossible to achieve, but people using different weapons is a sign that they've done something right. In Destiny, the amount of weapons the majority of people use is very limited.
