exept if you count in nighthold release in january and duration it would last probably 10-12 months not 5 so you just disproved your own theory congrats, gj
whther you liek it or not its clear devs treat Emerald Nightmare as t19 and nighthold as t20 /shrug
cant wait for early 2018 to see all white knights trying to defend blizzard how they planed from begining that nighthold will be 2nd raid tier so they could artificially put in number 3 on tier after nighthold and say 'hey what do you want we given you 3 raid tiers like we promised"
