You aren’t farming for tokens. You are farming for legendary items which means you are farming for legendary shards. What do legendary shards do? They serve one purpose: to infuse with other gear. Once you’ve infused to a certain level, there is no other use for the shards. You’ve hit a wall. There is nowhere else to go within the D2 economy. Have fun building your legendary shard stash, one disappointing loot chest at a time.
