Loot reroll

I have a suggestion with the loot reroll items. I think we need added to these is vanity drop rate increase. Right now nothing really drops in the old campaigns. Im thinking loot meaning all items vanities and weapons so why not make that loot reroll items include a vanity drop increase say maybe like 5-10% on certain items like relic items and 15-20% on elder items. Also reroll vanities would be nice when u do drop sometime. This way if ppl don't Care to grind black cat they can try missions and maybe get items easier.
