They need to work on the basics first before they move onto any other forms of PvP.

I would like them too, despite not really wanting to say it, look to WoW for some PvP inspiration.

As it stands we have "Alterac Valley" in the form of Cartaneau flats. Albeit, something that would require going into the enemies base and gradually taking it over until you reach their HQ and then fighting their commander would be nice

It would be nice to see some capture the flag. It would be team A vs. team B and would pair you against a random GC. So you would be Flames and would be matched against either the Adders or the Maelstrom.

Some other forms of PvP would be nice too. Something like Arathi Basin where you just need to hold points (I know flats is basically that, but I think it's more like what I mentioned before).
