In all honesty, I do not believe normal Event Team Members should get access to NPC's and the spawner. Due to the fact that amount of entities/vehicles that are spawned in during playtime on the server (ex. printers, cars, weed, props etc) Even with the proper training and documentations, there will always be instances where an Event Team Member will go overboard with the amount of NPC's and will have no idea what they're doing. Trust me, during my time on ImperialRP which they use NPC's very often there was always time where somebody would spawn in the way too many NPC's and end of crashing or heavily lagging the server. Both NPC's (depending how much) and the entities and vehicles are used at medium range player counts can cause large amounts of lag. That is why Lead Admin+ are only allowed to use the NPC spawner as they are more experienced with what the server can handle and such. I do not trust people with little to no experience with the spawner even with the right amount of training, documents and rules.
Other then this I believe there should be changes on how the Event Team is ran as of now and event are extremely repetitive and there should be more ideas with events and should not follow a certain based format with events.
