[2022] PvP Reward Track Tagged Gear

@xyo Since we are limiting each notch in the PvP rewards track to three reward rolls, we implemented a simple weighting system specifically for this feature. When you get a weapon roll it is giving a roughly 50% chance that it will roll a weapon you have equipped in your primary or secondary slots, including shields as well. There is currently no biasing by armor weight. We’ll look to tune this based on feedback and are investigating how this type of system can be more broadly applied in the game.
