Imagine if you could get extra Trader’s Tender for doing content in the game. Think Legion Legendary drop chance rate, something you can’t actively farm for, but would be a nice bonus reward to get. You’ve been farming the raid for weeks, or you finish your 30th M+ dungeon for the month and you randomly loot an item that grants 100 extra Trader’s Tender.
It would still make the Trading Post special, where you can’t buy everything, but would contribute to those nice moments you have in the game.
