Everyone that started off from exp launch should be getting around 200k a day in game...whether or not you want to farm it is another question.
last night on hc and mythic run plus WQ and WB...was insane amount of AP...
If you invested the last 3 traits of fire ...for the Armour...well that's just plain dumb..that would have been better been put into the other 2 artifacts.....right
There is no 'enormous' amount really...so long as you didn't try put 5k AP dailies/drops etc into a 1million upgrade....because that's just stupid.
So if people want to backlash...then they really need to ask themselves if they actually worked out the best route to level up their artifacts...
