The map pool right now on vanilla servers its ok, but it can improve, also most of the community always votes for mc city, dolls, haven and sometimes seriuscraft. Literally found this map pack on steam by googling "ttt minecraft maps", my recommendation is to atleast add 2 or 3 maps of this pack. The map pack can be found in: "https://steamcommunity.com/sharedfiles/filedetails/?id=817337670"
bump the link that OP provided is a great collection of MC maps for vanilla, our vanilla currently has boring overplayed maps and theres only like what? 7 maps for vanilla? we need more and then we can introduce longer lockouts to stop maps being overplayed
Not going to go through all the maps but ye, definitely could do with an improved map pool. Alongside that add Jondome back to standard Vanilla and not just Eu (I'm pretty sure it's still not in).
