I would change some things in towny, make it more custom and unique. We are a towny server, yet I don't see a lot of changes in towns.
I would add The Walls, Skywars, and TnTRun. That's how we keep people on the server for increased amounts of time, and it could be made so it is extremely unique and gets even more people on the server.
I would remove Laser. The most unpopular gamemode in my opinion, and it isn't great for the server. Laser just hasn't been good since the first couple weeks, and new maps won't help it for more than a few days.
I would remove the Club Meep at spawn, very useless and unpopular.
I would remove the Docks and Alpha6 infected maps, change/add new kits (especially nerfing/removing the witch kit, or at least the poison potion), and add new maps and perks. For the maps, a new one made and removed every month.
I would make minigame coins an overall currency. So for parkour, HG, and Infected; all coins which you can trade in for Meebles (maybe /warp tradecoins).
New HG maps. There hasn't been a new one in a long time. Also, a new one made a removed every month.
Remove the maps in HG that are huge, or make it that over time a border closes in. HG shouldn't be a game of hide and seek.
I would make it that there are multiple supply drops in an HG game, scattered throughout the map in random spots (randomizing every time).
I would add gold ingots/nuggets, XP bottles, and lapis lazuli in the games. XP bottles and lapis for enchanting, gold ingots/nuggets for gapples.
In HG, I would make it so that if a game went on for 10 minutes, everyone alive would be teleported to spawn, with a very small border, for a deathmatch. (Like good ol' times)
I would remove most of the parkour maps, maybe all except city, and make a whole bunch of new ones. I would make it so every month one was removed and one was added.
I would look out for more techs and architects so that the server can get better and better faster and faster.
I would add make a helpful thread in the applications section, like Cooleys used to have, and other people as well. Just like a guide of how to make an application, what not to put, etc.
I'll probably end up editing this as I think of more ideas.
