It's less about what is available and more about how content must be presented. Contrary to popular belief, Instances are not created to prevent competition, they are created to save resources. You sacrifice variability to ease the load on a single server. If you allow for a single instance to have a large set of variables you instantly take away any and all resources saved by forcing your servers to store and load a large number of different versions of the same instances. Open world event only occur once at a time. You can have all the variable occur at random, but only one set will ever happen at any given time.
