As of me I really want to improve the bhop server, it is one of my favorite servers out there for least, here are some suggestions you can add for the server. (I will be adding more suggestions)

Low Grav - a mode that has a low gravity as of it has a bot everytime you click low grav in the style selection it wont work.
A More Difficult Ranking System - i love the mm rank but having a player that beat a map in 10 mins on a 1 min map and getting a rank that is for people for rank 50? should be way higher, this could help the server have a more stable player count with players contantly trying to improve their time to the world record bot.
Weapon drops - everytime when you drop a weapon sometimes u can pick them up, meaning players are throwing their weapons in zones you cant get to. please make it so the weapons will disapper.
View Bob - when you get shot from a player your player viewmodel bobs so its extremely annoying and difficult to bhop.
!options - this command will have commands such as remove door sounds (when you jump on a block it sometimes make a sound). remove gun sounds, this can be very annoying for someone trying to go for a flawless run.
Store System - This is a fun little thing it will have models, hats, and misc to buy them you must have credits, to get credits you have to play the server 5 mins to get 10 credits, beating a map will give you 5 credits. You can check your credits at !credits and go to the store with !store or !shop
