The main topic for Classic at the moment would be whether the game is actually harder or just has more redundant activities you have to do before doing the stuff that's really fun. This is actually a good discussion to have, and not just for WoW, but gaming in general. The main sticking point for now, as most people are on (relatively) low levels is the breaks between killing mobs, especially for mana users. In the beginning it's actually refreshing having to think about what you can and can't pull, not just running into a bunch of mobs and killing them in *insert current optimal time to kill Blizzard determined is the most fun*. The food/drink breaks after a few (or even one) mobs provide time to actually look around the scenery and the mobs you're facing, and while there isn't much strategy involved at these levels, you still at least pretend to plan out how you're going to get to that quest mob without being killed by the 4 random ones surrounding them. Not being able to pull whatever mob you want, and actually having to check what mobs are there when you don't have interrupts yet (casters tend to be a nightmare) is definitely more difficult in a real way than what we have today. As a caster, having to actually think about which spells to use based on mana cost (and perhaps even using lower ranked ones) is definitely more difficult and requires more engagement with your character than we have in modern WoW.
Brack played every Blizzard game, but World of Warcraft will always be closest to his heart. World of Warcraft changed Blizzard. When the game launched back in 2004, the company had 300 employees. Currently, they have 4,300 employees. They've got more games that they're working on now than at any other time in the history of Blizzard. Not every game released by Blizzard needs to cater to everyone. It's fine if you don't like a certain game. Mobile is a platform on its own, similar to consoles or PC. The games they're developing for mobile are going to provide an authentic experience, but mobile titles aren't trying to replicate PC experience. Nintendo has been a great partner and they are happy with how the Diablo III panned out. Switch has some unique properties that consoles don't have. From a player perspective, Brack's proud of his guild downing Ragnaros back in Vanilla. Kael'thas was also a hard boss during the Burning Crusade, so defeating him was also considered a feat for the President of Blizzard. Doing the Argus patch in Legion was quite the challenge. Mists of Pandaria was the most misunderstood expansion. They've been experimenting for 15 years with content schedule for the game and figured out that the two-year expansion cycle with 3 major patches is the right thing. They were thinking about making Argus an entire expansion, but ended up not doing so.
There are two parts of the quest chain for each continent. The first part involves defeating numerous Master Pet Tamers, and the second requires you to triumph over the Grand Master Tamer. After you've bested the Grand Master Tamer, dailies from each Tamer will unlock for that continent. All the dailies continue to reward experience for your companions, however only the Grand Master daily quest will reward the Sack of Pet Supplies.
