I will agree that trying out new maps is good but as console said it's a pretty mixed bag, villa and clearcut are both really poorly optimized and cause bad FPS lag, along with not playing out that well or being particularly interesting. There may very well be more new maps that are better though, we should definitely continue to have new map cups and test things out. What I will say though is this: instead of having a foregone conclusion that badlands and granary are the most hated and need to be removed, we should give them the same chance as the new maps to be voted in. If xattuu and others are right and the new maps are just better, let them win by their own merit and not by excluding the old maps from the ballot. Prolands fixes some of the issues from the original badlands and should definitely be tried as well. I think we should all be a little more open minded instead of assuming that the other side is completely wrong, there's pros and cons of new maps and old maps.
Personally that I much prefer badlands and granary to clearcut and villa, and I would like to see reckoner tried as well potentially. Also, I don't like this argument that just because a map is being currently developed it should automatically be better, let the quality of the map speak for itself. Just because something is being developed doesn't mean it's in a good state now, in fact, playing maps like villa and clearcut in the league I think has cemented people's opinions of them as bad and if they get updated later to fix current issues people will have the bad taste in their mouth still and be apprehensive to play it again. I think clearcut could be fixed if it was less one-dimensional and the cave you can hide your medic in for sacks was removed/restructured, but those would be pretty big changes to make while it's still in rotation. In my opinion we should just vote it out for a season and let the mapmaker try out some different changes in betas, and then vote it in again if it's better.
Edit: the 30 minute stalemate between 7 and EVL was much more to do with match nerves and high stakes of both teams not wanting to lose (also vaccinator last memes by ckj) than the map inherently being flawed. I can't blame them, I wouldn't want to be knocked out of grand finals due to a back cap, but at the same time if either team had taken more risks it would have been a different game. 1 man sacks and spy plays are not exactly the highest amount of effort/commitment you can put into breaking a stalemates, most teams do 2 man sacks and or uber exchanges now which are more risky and help break stalemates better. I've had some of the most back and forth and exciting tf2 matches of my entire time playing on badlands, yeah it's hard to push last but that's true for both teams and it means if you actually do break it you really deserve it. Also, the meta has developed a lot over the ~13 years of the game, there are so many different possible midfight strategies and ways to push each point. If the lower divs really hate it that much that they don't want to re-add it, I would like to see a vote to add it back for invite only like bagel is this season. We have so many maps that play almost exactly the same and are just variants of cp_scout, having maps with different flows and class balance is good for the game imo.
