I hear ya - that was a concept I was considering too. I steered away from it because I felt that it seemed to close to gun game from CoD and other games, which are simply kill ladders to better guns. My philosophy behind the way I wrote it out is it allows anyone to get in the mix, and doesn't alienate those who might not be as good in PvP and leave them with lesser weapons. That said, those legendary and exotic crates would grab the attention of many players, and will require decent skill and awareness to walk away with some of those weapons without getting repeatedly obliterated. To each their own however
