While I haven't been playing dayz since it came out, I have to say hands down the main reason I don't play vanilla anymore is for three reasons. 1. There isn't enough to do as many others have already said, once you get a car, a camp, some decent gear and a chopper... there isn't really any reason to play anymore aside from hunting other players... which leads me into my next reason. 2. I am a terrible bandit, don't mistake that for me being a bad player.... I am just too damn friendly. Many, many times I have let my prey leave my sights after having a nice chat with him or giving him a weapon or some food or just being friendly to the guy..... I was supposed to shoot him dammi!(or at least take his gear not give him mine!!) but that being said since I am a terrible bandit I tend to look for servers that have other things for me to do that occupy my time instead of hunting down everything with a pulse once I get some decent gear. Such as but not limited too: Base Building, AI Missions, Crafting, Raidable AI Strongholds, ect and at least in my opinion it is more rewarding for me and my friends to spend 2 or 3 hours trying to fight our way into a stronghold than it is to sit on a hill at North East Airfield and snipe every player who comes down to check out the barracks for gear terrified that someone is going to shoot him the moment he walks out the door with his loot. 3. Lastly the other reason I avoid vanilla servers like the plauge is simply because they feel so outdated when you play on them imo, for instance I have been playing Overwatch over other servers lately almost exclusively because of the new smoother animations and updated weapon sounds. Normally I don't care about things like that but when a version of a mod looks/sounds/runs better than another version does then it becomes hard for me to ignore. Honestly I see the modding community as what has kept Day Z and its playerbase from stagnating and fading into obscurity. They are what are keeping DayZ going and pushing the boundries of what can be done with this game and bringing new and innovative ideas into the mix that enhance the experience for most if not all in some way.
