I've played WoW since 2006, but took a break in late May/June, because I had some other things I wanted to do. Now I'm renewing my time and excited to get back into the game, because despite some flaws, it's a game I have so much experience with, and so many good memories. And I still really like it.
Anyhow, I feel really out of the loop regarding changes/updates since I last played, 3-4 months ago. I understand there is a new raid (which is also in LFR), a new island (not sure about the purpose of it) and I also believe there's heroic scenarios, but I think those came around the time I took my pause.
What should be the first things I do in game to catch up, and what are the new things? I assume the new raid has a new coin-like thing for extra rolls, that I need to get?
Really appreciate answers that will shed some light onto this.
