I have a suggestion (since the templates haven't been fully finalized, this is what happens): let's select 4 of the most popular templates – let everyone suggest their options, and run 5-8 rounds on them! I think the essence of the game won't change, but the arguments will subside (hopefully), and most importantly, everyone will be satisfied! :)

I doubt that each participant in the tournament has played on all the templates even once. And the templates are actually well-developed, and more than one tournament has been played on them in the league. Almost all of them are interesting; each has its own unique feature, even the Diamond one. It's just that everyone has different tastes – some people like long games, while others prefer rush strategies.
I think that this tournament should be played on all the templates, and in the future, we can vote to select the most popular ones.
