Elemental items (Primals, Eternals, etc.) can be a good source of money, because they are always in demand on the AH. See which mobs you will most benefit from farming, then set out for a few hours. In the process you will also most likely collect significant vendor trash, and may get other profitable item drops as well. Note, however, that older elemental drops usually lose profitability compared to newer ones, i.e. Primal Water sold well to level 70 players in BC, but sells far less well to level 80 players in WotLK, because level 80 gear requires Eternal this'n'that.
It’s a name lovingly given to me by my little boy, when he discovered I owned 1/4 of the wealth on the largest server in the EU.  I’m proud of that, not arrogant.  You can be “royalty” too if you put the effort in and refine your skills.  One day, someone will become the Gold Emperor, and I will be extremely proud of them.  That’s why I created a Hall of Fame, so you can journal your way to the top, see how far you’ve come, and be inspired by other member’s progress.
Both Burke and Danuser repeatedly stressed throughout the course of the interview that the Alliance is not a monolith of views and approaches. However, one character has taken the spotlight and the reigns of action: Anduin, the new high king. “With the death of Varian in Legion and the rise of Anduin to Kinghood, we’ve spent a lot of time on his character and showing his growth,” says Danuser. “He’s a great character, and we wanted to show how he interacts with big figures in the game.”

Only really to expand on Gráinne's comment as regards the 'collecting' and 'roster development' sections - which are, as said 'distinct' although they are intrinsically linked - I would like to point you in the direction of the in-game Achievements > Battle Pets > Collect tab. There are a series of achievements called Raiding With Leashes, pretty much all of which can be completed via the auction house - if you have the gold/inclination - or by completing old raids.
