PvE Server Class Balance: Horde?

Introducing the girlfriend to WoW, sticking her on a Mage (she wanted to play Undead & Mages are pretty simple, plus who doesn't love chucking fireballs).
I decided to play a Warrior as I always play a tank & RIP Vanilla Feral Druids.
However, as I run about 70%+ of the players I see are Warriors. Granted, we're still low so those players may burn out on the Vanilla Warrior grind. But it got me wondering if perhaps there were more on the PvE server because getting raped by Alliance while you level is less of a threat (which Warriors are uniquely vulnerable to.) I would have thought there would have been fewer Warriors as the class is primarily so popular on Vanilla servers due to its PvP prowess once geared, which I assume is less appealing to PvE players.
Do we have any stats on class balance for the PvE server? I saw some great ones on the PvP server.
Or anecdotally, if Rogues are under-subscribed compared to the PvP server (for obvious reasons) and there's an abundance of Warriors, that could be a fun alternative.
