...very silly...

I'm asking again, directly: please discuss intellectual matters in private messages. At least respect each other on the forum.

...to give the right to choose a template,

Hmm, I don't play either Offb or League Championship, but, in my opinion, the way to choose a template in League Championship is much more rigid. In Offb, there's a choice from only 3 templates - players cross out one at a time. Closer to the end, knowing our strong players well, their preferences, and the statistics that are open to everyone, it's very likely to "guess" which template they will cross out. Just think a little before the game, browse the forum if you care.

...and then, based on the chosen template, choose a city for yourself, this is a solid advantage...

In most tournaments, this is exactly what happens - we choose cities, already knowing the template. But both know it, both choose cities based on the template... If blue chose cities for both, and red stood aside and picked his nose, that would be unfair. Usually, in such strong tournaments, players should be able to choose an acceptable pair of cities on any template. On the contrary (knowing the cities, choosing a template) is somewhat unusual, therefore more difficult.

...but the advantage of the red color is very debatable, statistics are powerless in this case, since in most matches of the first rounds, there is a large spread in skill among the opponents.

Statistics are no less powerless than speculative reasoning about red and blue templates and other theoretical arguments. I tried for many years to identify a correlation. Only a direct dependence of the % of wins on the skill and experience of the opponents was found. With equal skill, the random number generator decides (and it can be merciless to any color) and random mistakes. When we played multiplayer, we had to put half the team in blue, half in red. The team players mostly asked to play red if possible; an extra day is important for a strong player...
On the other hand, if playing red is so unpleasant, then maybe the second player choosing can choose their color? I didn't find this in the rules...

...However, everyone is in equal conditions - today red, tomorrow blue.

Golden words, the rules are the same for everyone.
