According to Brian Holinka, we'll be getting something that any old school AV players will remember for Ashran, the new PvP zone in Warlords - namely, the ability to create a mob that makes the other faction's day considerably worse.
It just gets my Ivus senses tingling, you know?
@millerwolf1990 We're planning on having something like this in Ashran. A giant mob that your faction can build to torment your enemies!- Holinka (@holinka) June 12, 2014
I realize that this may be the nostalgia talking (oh, what a potent drug that can be) but man, I hope it actually is a giant fel reaver. I have no idea how that would even be possible, but I still hope for it. Ashran is shaping up to be something we've not had in the game in a long time, a true free for all, and I'm very interested.
