Granary pro which we play is still being updated tho and prolands is a thing why not give useful criticism on those maps and identify and see if it's possible to fix their major flaws? By the same token we aren't just throwing out bad maps like cardinal why not give specific reasons and things that can be changed? Long post below identifying the flaws I see and potential ways of mitigating them (sorry there's a lot to say maybe I'll edit in bullets/tldr later)
Badlands:
I think there are some key issues by all means but they're definitely workable. I have placed so many super fun close badlands matches I think the flow of the map can be stale and boring but there can also be super back and forth last to last games if teams are willing to do unconventional stuff like push valley into mid and go for 3 man sacks to force them to push our of last and then fight second.
Though as a medic I personally find it super hard to play and I nearly always die on mids, that's not really a reason to just all together scrap it. Yes it is certainly not a fun pug map cause back caps and the need for coordination and slowness making last pushes hard, but in league play with an hour to widdle down their defenses the better team nearly always wins badlands and I don't think this "boring" ness should be the main consideration. Yes most people don't find it fun, whereas EVERYONE though cardinal wasn't fun but vel and froyo would be willing to play it cause they had practiced. Even though it's not fun for me, I think it's good to have it in the pool because it adds variety and if teams want to choose it and play it there can be really good matches often times. I don't like it too much myself but to win sure we will pick it if we are better. It's a map where teams can play methodically and strategically (vs entirely dm you have to play smart) and rewards the best coordination as a team and knowledge of the map/experience doing the various non conventional pushes. It's also a very strong soldier map which is another thing to consider.
Granary is a very slow map yes but I am unsure what exactly is meant by a "modern flow". New maps such as sunshine and metalworks are both known to be INCREDIBLY stalematey, and without uber against a sentry gun their lasts are also very hard to break similar to gran and badlands. Hell even snakewater last can be super hard to break and in Europe people seem to hate that map for the reason that people pussy hold last forever, whereas we generally play it more fast and I don't think invite teams have such a problem with that due to our playstyle and developed meta. We've seen plelenty of matches this season and in the past huge stalemates on sunshine second with a sniper trying to peek and just doing 1 man sacks over and over again, same with process and virtually any map (other than via which is THE MOST FUN AND FAST PACED AND DEF SHOULD NOT BE REMOVED) if it's in an important match and people are afraid of losing. There have also been many granary games that have been super close and interesting to watch (never forget the legendary 5-4 tcm game), which shouldn't be discounted. If people really unanimously agree out with granary (THERE SHOULD BE A POLL ABOUT SPECIFIC MAPS WE WANT GONE NOT JUST #) im fine removing it but I do think there's potential for dagger to fix some of the issues with it (see below)
There were talks to keep the cow mangler in as not to nerf soldier class even more cause it's the worst class, but nobody mentioned the how bad it will hurt soldier class by removing badlands and granary two strong soldier maps (which are by no means super easy to play as a soldier well, just that good experienced players know the intricacies of them and can have lots of impact vs good soldiers who aren't as practiced or knowledgeable in the maps who won't be able to shine as much) and adding a nearprocess/sunshine/snake clone (propaganda) as well as a mid where soldiers literally just get denied entirely by scouts and cannot double bomb vs good scouts cause there's nowhere to properly land on (logjam, people generally thought the mid was bad, esp for soldiers).
