There I was last night, turning in a quest when it happened, I made it to level 100 with my first character in Draenor.
Certainly not the fastest run to 100, but it still seems like it went by pretty quickly, given I how much I dawdled and played other games, plus spending a few days reviving my computer.
One benefit of moving a bit more slowly than some is that I had more time to accumulate garrison resources, so I was able to jump right in and upgrade my Town Hall to level 3.
Now I have a whole bunch of things to unlock and upgrade there. I have to work on some pets to take on the three battle pets in the garrison, a requirement to unlock the menagerie. I have a few level 25 pets, but as with Pokemon, you can wander through the world and succeed with any number of combinations, but once you get to a boss-like fight, you need the right set.
