The problem is [b]saturation[/b]. Allow me to explain: 1) You have been able to carry over the previous 5 years worth of hand cannons into each new expac. 2) You now have 45 hand cannons that are all viable in the new content. How do you make those 45 hand cannons different enough from each other that you have a [u]MEANINGFUL[/u] choice between them? How do you make the 10 added hand cannons with the new content feel [u]MEANINGFUL[/u] when you acquire them? The fact is, you can't, because your field of options is now saturated. When that happens, humanity defaults to what they know, which will be their favorite.
