I've said this before but I'll say it again. We need a weapons range at the tower where we can experiment with gear and such. Here's how it would be cool:
1. You could equip any weapon and it's fully upgraded (on the range only, you still have to upgrade it in the game on your own) so you can see if you like the percs and other characteristics.
2. You can go to any vendor and test fire up to 2 vendor weapons at a time without buying them and when you equip them the weapons are fully upgraded.
3. There needs to be enemy's (that are dumb and don't shoot back) so that you can experience percs that deal with enemies by number and how close they are to you.
4. You have the ability to buy ANY weapon at a vendor FULLY UPGRADED for 200 legendary marks.
5. There needs to be a crucible area where you can shoot at MOCK guardian's to see how a weapon performs in PvP.
If we could get that at the tower(s) this game would be in a league of it's own once again.
