Aka play the game and have loot rained down on you. seriously I suggest a hard hat.
This happens pretty passively now. My warrior who I ahve never done any island on or anything is level 70
This is a fair complaint about 8.2 but they made those rep grind half as bad for the old ones now by only needing revered. The only essences that you need now are the new ones which you can get rank 2 without rep anyway.
Do cool story quest line. or on alts skip large chunks of it.
The time consuming part is clearing the 2 zones which give the currency for visions anyway.
These are awesome if you want to push them or very very quick if you just want your upgrade. They take 5 mins if all you do is walk in and kill the boss.
This has been earn able for 31 weeks (yes I looked it up)
