Well, just essences alone should be a step in the right direction.
But it just is very weird to read to different posts agreeing and disagreeing on the same things at the same time.
I am all for more alt friendly content and everything. Getting all Zandalar proffessions was a pain aswell due to having to level some reputations to be able to level a proffession up beyond a certain point.
So i would agree on making more stuff account wide, so that is all fine. But for now my focus is on the essences.
Essences are just a great example to tell and show Blizzard the system is really flawed and not friendly in any way if you play alts.
