During Labyrinth event one detail stuck to me the most, the token reward from the leaderboard for bound kraken item from vendor.

I thought it might be a good idea to reward tokens as lb prizes ( Gold token for top 5/10 , Silver token for top 25 , and bronze token for top 50)

These tokens can then be traded at vendor in the respective event zone for a lb prize from previous year reward pool or latest addition of prize of that current event.

for example, gold token from Halloween can be used to trade Halloween top 5/10 reward from previous years, And for winter event you can trade for winter lb prize pool of respective finishing standings.
