“We got to play on the server for a little while,” he divulges. “It's really cool, they did an incredible job of building an experience that feels classic and authentic and that's incredibly hard to do.

“The leadership team got together and we did a Stratholme run. John Hight [production director on WoW] was a Hunter and had a level eight pet and pulled half the instance, wiped us a few times. It was like, ‘why is the whole instance pulling? Oh it's your level eight pet!’ J [Allen Brack, VP and executive producer] was our priest, he’s like [casting buffs] and then sit and drink for 45 seconds, cast again, sit and drink,” he chuckles. “It's funny, we laugh at all that but it was a very moving experience because it's nostalgic and we all have very fond memories of playing that, that's when we were hardcore and all that stuff.”
Lol, nabs. I mean come on, lvl 8 pet?

Good to know Blizz devs appreciate Nost's work. Awesome stuff!
