Yep, finals/semifinals should always be different to the other matches, because it gets the most attention from viewers.
Also the maplist wasnt that good. We basically played only pforest whole tourney, because there werent any other maps we would prefer. If there was eg. renoir/sass added, it would lead to wider map choices at least for our team (ye we played wobluda, but that was just our bad, we didnt decide on elims we just wrote w/e we thought of and ended up playing wob, even tho it wasnt really tactical ^^).
As for the server choice, we had the right by rules to choose server (we registered before you did). Because we felt like it wasnt fair to play finals on eu server, we offered you to play BO3 while switching servers.
The rule about server deciding is pretty weird too. I think you should make it that team which is seeded higher in brackets gets the server choice.
And more thing, having even number of maps makes elimination weird, you basically deprive a team one elimination.
Leme give you an example, if there were 4 maps:
Team 1 eliminates 1 > 3 maps left
Team 2 eliminates 1 > 2 maps left
Team 1 eliminates 1 > the remaining map is played
so not only Team 1 gets to pick the map they want to play from the 2 remaining, they also can eliminate 2 times while Team 1 eliminates only once > not fair for the Team 2.
Otherwise good tournament, those issues i pointed out were kinda minor and we still played it through and it was fun to play. Just fix the things above and it will be even better next time.
