I'm gathering that Drak'thul was changed from PVP to PVE due to massive population imbalance. (Note that they gave free transfers to PVP realms for players who still preferred that type of realm.) In another thread, people mention that alliance got overrun by horde on Drak'thul and were never allowed to level, so alliance became almost non-existent.
Due to a recent article by wow.com that linked to an older article, it seems that PVP realms have been on the decline for more than a little while.
Now that we have precedent for this sort of action, I must beg the question -- when does Zuluhed get to be fixed?
It doesn't have to be soon. But my birthday is in November.
