Give the removed death tag maps a second chance

Hello! I want to give you a link to the official Mineplex Map Database here. An explanation of what this information is can be found on this thread made by Dutty, the current Build Lead. You can see on the spreadsheet on the "Removed Map Databse" tab that all three maps you mentioned ("Waste Land", "Enclosed Library" and "Mayan Ruins") were removed for the reason "Poor Gameplay". This is likely due to decisions made by either the build team or the Game Insights community discord and official Game Insights players. Learn more about Game Insights here.

You briefly mentioned reasons you thought the map might have been removed and fixes to them, but unfortunately without knowing exactly what "poor gameplay" meant to each individual map, there aren't fixes we can propose. There are 13 active maps for Death Tag and only 3-4 removed, so I think there is plenty of variety currently available.

I do understand the nostalgia, but it is likely a better use of builder time to create new maps for this gamemode.

 

Something that didn't make a lot of sense to me was Shiro vs Wasteland vs Mansion. (I've only seen Mansion maybe two or three times so pardon me if I'm wrong here.)

Just from a glance, I'd say it's safe to assume they're the largest maps in the game, removed or not. However, Shiro kicked the bucket rather quickly, Wasteland stuck around for quite a while by comparison, and Mansion we still have. I'm assuming that it has to do with the amount of detail with the map, along with the flatness. From what I remember, Shiro was completely flat except for some areas around the edges I believe. I'm only referring to ground level for this, while also ignoring anything less than a five block height difference. Wasteland had a lot more elevation changes so I think that's why it lasted longer, but it had some unfair camping spots so that might contribute to why it got scratched recently. Mansion looks like the best of the three, lots of elevation changes and some great detail for both gameplay and visual appeal so I'm guessing it'll last much longer.

Mayan Ruins always seemed a bit off to me when compared to the other maps. Might be due to the severe elevation change (practically half the map) in such a small area. So map flatness could play a part in removal reasons, but having it too extreme could be a cause as well. Just a thought.

With Enclosed Library, I've mentioned that the outside of the library was meant to be used. I've also got a copy of the map and I run around once in a great while since it was my favorite. Looking back on my previous statements there's something worth correcting. While it would be better to open up the outside to give runners more room, it wouldn't make it a lot better. The more I searched around the more I realized that getting in/out of the library isn't exactly easy. Just small openings in the ground or the upper window which aren't very wide. It's very easy to get caught or ambushed.
Maybe having two or the doors opened, or perhaps collapsing a wall (since it looks old and worn down) would be a good addition.

As Dulciloquy mentioned above, we can't fix the issues since we don't know exactly what the reasons for 'poor gameplay' are. Taking some educated guesses can help but it isn't a guarantee to catch every problem. In my opinion, it might be best to rebuild the maps from scratch (using the originals as templates but change things up while keeping key areas or features relatively the same) instead of taking the current build and trying to edit a few things. I don't know who would have downloads of those maps outside of the build team, other than henrikberg. I remember he had all the downloads but not sure if there's a way to contact him.
Well, maybe you wouldn't need the originals as a guide if you remember it well enough. Some of the maps just need to be rebuilt from the ground up, since the ground itself was probably an issue. All things considered though, these are all just my opinions on the matter.
