Adding dj back would be a dangerous move
I suggest to remove Semi Clip to make gameplay more entertaining like boosting and feel nostalgia back like we had before.
Removing noclip and adding colisions to the game will be a great move, because i don't really know if any of those other ZE servers used collisions, and if we add those collisions back, this would be great to make our server feel unique to those modded servers.
Adding coins for exchange to getting escapes or VIP for 1 day or 7 days is great way to encourage playing the game. Also, i suggest adding the buy menu for buying ammo, HE grenades, fire and freeze grenades (with no impact/homing/laser modes) with coins.
Also, i saw that when a player wins the game and he is alive, the 1+P.O.W message on the center of the screen is conflicting to 2+ESCAPES, so i would suggest to make that message appear a little lower than escapes.
Plus, the /get message that appeared on the screen if you had synced account before could get back, but to appear on the lower left menu where are the messages, and to tell you every round that you have unclaimed free escapes.
And yes, make the Simple level info option on the menu functional and remove the total achievements stat
