Q&A Recap
These are some of the more important points from the Q&As today.
Warlords Release Date

Another MoP patch would delay WoD, so Patch 5.5 isn't going to happen. The entire team is working on WoD right now, so any more MoP content would slow down development.
Q: "Typically after you announce something it is another year, but we are at Patch 5.4 now. What content do you have planned for between now and then?" A: "Any content we do now will delay the expansion by the same amount of time it took us to make that content. We are completely focused on making the next expansion and will try to deliver that as soon as we can, hopefully on a shorter cycle than players are imagining, but you never know, we will have to see."
Q: "Typically that would be in the Winter of next year. Does that mean it is a goal to bring it in to Summer or Spring?" A: "Well certainly the goal is before that, but we'll see, it is very hard for us to predict."


Dungeons and Raids

The new Flex loot model will work similar to how Master Loot does today, but the number of drops will scale based on the number of people eligible for loot in the group. The personal loot system won't be removed, you will just have to opt in to it.
The number of drops will scale well with the number of players, as each additional player gives you a higher chance to get another drop, up to where it is guaranteed. This ensures that are no odd breakpoints that will restrict raid sizes.
Mythic raid lockout is boss based, static id, nothing is changing from the current Heroic lockout system.
The game has a Raid Browser that no one uses, so in WoD it will be expanded to support killing world bosses, doing achievements, finishing Shadowmourne, or any other activity. This will support cross realm groups and encourage people to do PuGs rather than completely random matchmaking.


Quests and Leveling

You can technically buy as many level 90s as you want if you buy another copy of the game, get the level 90, and then transfer the character to your main account each time. The team has talked about putting a level 90 purchase option in the store, but it hasn't been decided yet.
There will be a legendary questline again in WoD. The questline will be a little bit more custom to your class to help with the lack of class quests. Class quests are very resource intensive, so at most we might see one or two in WoD. (Maybe Shaman)
Leveling in WoD will be a fun and fast paced romp through the zones. The team is backing off the idea that leveling should be a long grind.


New Character Models

The team hasn't decided how new character models will be released yet. It could have all of the completed race at launch, or they could be added every patch.
There will be no free re-customization for characters after new character models.


Misc

There aren't any plans for another WoW Annual Pass. It was a good idea at the time because getting Diablo 3 free made it a good deal, but it isn't a good for the the D3 expansion.
Recruit a Friend will be back next week.
The tertiary stats may be limited to a certain slot, like speed only on boots. It will be rare enough that by the time you can farm them progression races will be over. They shouldn't have a big impact on progression races.
Racial balance will be tuned again in WoD, trying to narrow the gap. Goblin and Worgen have better balanced racials than many other races right now.
