Garrisons are an interesting solution for player housing. At first it seemed as if they were promising we could place our base anywhere on Draenor. I'm glad they clarified it. The possibility of sending minions to get new recipes, new transmogrification gear and general loot, is interesting. Not enough detail was fleshed out to feel the warm fuzzy that these features will make it into production.
The quality of life improvements were appreciated. More details on how heirlooms as a collection will work would be interesting. Additional collections such as tier gear and recipes would be appreciated as future enhancements.
How about a release date estimate? We've heard their reasoning about not wanting to raise expectations prematurely. I don't agree with it. I work on multi-year projects all of the time and we can't get away with having a forecast for completion of any stage. Ultimately lack of news allows for the interest level to wane.
Finally, if there was no desire to bite off a new class or race, why not expand current race/class combinations. It was done in the not too recent past. I recognize there are cases of cognitive dissonance with some selections but there are races that have too few choices. Tauren could only be 4 out of the original 9. Gnomes were originally 4/9 as well but they are now only 7/11 (worst ratio of all races). Consider the cost of adding new class/race combos to Taurens and Gnomes. New starting zone trainers and ... a database update.
Here is what I would like to see in the future:
I think these things would really fill out the package and make an already good offering, Blizzard quality.
