HAahaha if garrisons triggered you somehow then you're prolly gonna hate Legion. They just renamed garrisons as "class halls" but not only do you end up doing more shit to farm garrison resources (they even take up World Quest slots), they even gate some of the class/artifact shit through the new garrisons.
Look familiar?
I actually liked WoD's garrisons. I levelled six chars to maxed garrisons to rape the economy before I quit.
So as usual, Blizz's remedy to the loudest squeaking wheels is the most toxic fucking grease they could find: instead of doing away with garrison gameplay, they just expanded the TIMESCALES for everything in your garrison so ppl don't end up having to come back to their garrison so often. So missions all take at least a day, work orders take several days and big upgrades take a week or more.
