Post by i***@gmail.com Right now the max level for garrisons is 3, but didn't Blizzard say somewhere that they were thinking of maxing out at level 5?
I certainly thought I heard talk of it increasing to lvl 4 at some point - won't be in 6.1 by the looks of things but perhaps later on.
If garrisons become popular maybe in the next x-pac we'll see increases to levels 4 & 5 tied in to either higher levels past 100 or opening outposts in new zones from those x-pacs.
