There have been whispers of some sort of battlegrounds matching system
in the past, without any real information on what such a system would try to match. Today, Drysc responded to a post with some additional hints
on the kind of the system we can expect. The system will only be viable with the new cross-realm battlegrounds system, due to the increased size of the player pool, and will attempt to match people with specific levels of gear together. It seems like such a matching system would be darned complicated, but if this really works, my Zul'Gurub-geared priest will be quite happy to not again be one-shotted by Ashkandi-wielding warriors.
