I think Bungie is really going to shoot themselves in the foot with this insistence that the PvE and PvP experiences should be as equal as possible. I've been saying for a long time that the only way to achieve proper balance in PvP is to have a standardized set of weapons for that mode. Because right now the perks on your gun can absolutely be the difference in you winning or losing a gunfight. Or some archetypes are just impossible to balance because of their rate of fire. They either kill too quickly, or too slowly. So the only way around this is to let everyone have whatever toys they want in PvE, but for Crucible say "This is it. You get three or four of each weapon type to choose from. These are the stats, these are the perks. They don't change." And then have a mayhem mode where anyone can bring in anything, just to keep everyone happy.
