If PvP is a training ground, then don't allow the regular PvE weapons. Instead, each week or month or however it is rotated have pre-determined load outs that players choose from, and you can rotate certain nerfs or buffs as well. Before landing in the crucible you are taken to weapon room where there is a variety of pre-determined weapons, you choose your load out and off you go. This could be time consuming, so cap it at 5 minutes & if you haven't chosen then the player is assigned a load out. This could be a good way to feature certain weapons and get players away from their crutch, and it kind of balances things out. For example, I am not really a Pulse Rifle guy but after a few rounds in the crucible with a certain Pulse I realize that it can tear some ___ up, so going to use that in my next patrol. Also, a shooting range would be kind of fun. You head into the range, choose any weapon that is available and fully upgraded, and run some challenges to see if you like. Maybe you try out a Raid specific weapon, realize it is BA & that gets you to doing more Raids. Or, there is a bounty specific weapon that has some major grinding before you get it, so test it out in the shooting range and determine if you really want to grind for that thing. I don't could be a terrible idea, or sliced bread.
