It just occurred to me that the leveling and professions changes are going to mean that Warlords Of Draenor is going to be the default place to level alts, for a couple of reasons:
1. Draenor Treasures are an extremely fast way to level, and pathfinder requirement is being removed, meaning that everyone will be able to fly in Draenor, and therefore level by picking treasures
2. Relics of the past are going to make all old-world crafting reagents valuable again, which means that Garrison welfare mats will be valuable. Which will mean that it's going to be well worth building a Garrison on all your alts, and equipping that Garrison with a trading post.
So who else is excited about spending more time in your Garrison in Shadowlands? I know I'm sure not!
