A dedicated player has already collected every Tier 2 transmog set available in Patch 11.0.5 and it cost them 320 
Bronze Celebration Tokens!
Tier 2 Set Discounts
Your first set is the most expensive one and costs 60 tokens. After buying it, you will get the 
Upgraded Apparel achievement that reduces the cost of the second tier set to 40 tokens. Upon buying your second set, you will receive one more discount via 
Classy Dresser, making all subsequent tier 2 sets cost only 20 tokens.
As mentioned above, all 13 sets cost 320 tokens.
Update: It seems the player deleted their post and Reddit profile in the meantime.
Buffed Bronze Token Gains and Additional Sources
When you earn your first 100 Bronze Celebration Tokens, tokens will start dropping from:
- Blackrock Depths raid bosses
- World Bosses
- Classic Timewalking Queues
- Codex of Chromie Queues
- Korrak’s Revenge Dailies
The Player’s Strategy
Blizzard significantly boosted token gains this week, helping players quickly reach the 100-token milestone and unlock even more ways to earn tokens! The player simply farmed Timewalking Dungeons for the remaining tokens to buy every single set.
