I like doing the race once a day; it’s kind of fun.
And the vendor is amazing.
But for these types of events, it’s nice as a player to have an outlet for excess event coins. It’s a common thing in most games.
Even if it’s something very, very unrewarding, like say we exchange 100 tokens for 500 silver, even that feels a lot better than having 20k tokens that just go poof when the event ends.
I know there’s a lot bigger issues, and this event is just some casual fun + really nice free stuff on the vendor already, so maybe this is just a suggestion for future events.
