Hey! We appreciate your idea and we see what you're getting at, but sadly we won't be doing this type of tournament for each season.
The Winter Waltz Tournament is set up in this manner to be unique and something for all players to look forward to at the end of the year. Having other seasonal tournaments would take that away from the Winter Waltz Tournament.
We are always trying to have other interesting tournaments and ways for players to get involved throughout the year. An example would be the tournaments during last year's May the 4th Event! While a Spring, Summer, and Autumn Waltz is not something we're looking to do, we can try to incorporate other types of tournaments into events and other things.
Thank you for your suggestion!
