So my earnestly laid plans of getting my Garrison set up and then leaving it behind, to quickly level to 100 were quickly waylaid by a nasty habit of messing with my Garrison. So I'm sitting at level 96 instead of 100, but I've got upgraded Tailoring and Enchanting buildings and an upgraded mine. And I'm amassing tons of ore to send to my blacksmith and jewelcrafter and engineer. I've got almost a dozen followers, 3 of them epic. I've done a bunch of different Garrison missions with my followers and gotten some cool stuff out of that as well. I'm cutting down trees for my lumber mill and hunting down seeds so I can get my herb garden up and running. (Note to self, need to find an addon that shows my herbalism notes even if I'm not an herbalist).
I'm running across various zones search for just the right follower. So I've now got the appropriate followers to assign to my tailoring and enchanting buildings, so I now I need more followers to go on missions, since those guys now have other tasks.
I'm not as close to 100 as I thought I would be, but I'm having fun with it.
I've not gone the goblin route of trying to make as much money as possible in the early days of the expansion. In part because I'm already sitting on a comfortable cash pile, and also because, with my Garrison pumping out a steady supply of resources for all my various professions, I really don't think I need it. Stuff is getting churned out for later use.
I do want to run my inscriptionist through pretty quick so that he can start cranking out new glyphs because that is typically a pretty lucrative market for me, and I'm probably going to want the Darkmoon Card trinket at least on my main.
So we'll see how it goes as I continue to level alts. I think the next one will be a bit easier to go all out with, so I may have a little bit better data on leveling speed. My one after that was supposed to be of the official "faffing with Garrisons" variety, so I may just swap that with the plan for my main.
