The apparent flexibility of EAV is at the cost of simply horrible query complexity. The result won't be maintainable, and the benefits of allowing support of low structured data is illusive (like an oasis in the sahara. It'll disappear when you actually get there.) Much better to do a thorough schema design beforehand, and if change is needed then update the structures as need be, instead of using RM as some sort of filesystem housing an entity-attribute model.
