I am returning to the game from a long absence (ARR) and I am working my way through HW. I am learning all about master recipes, specialisation and scrips and wondered if any of this is still relevant in SB..?

I don't want to put a lot of effort into getting the lvl 60 gear (blue) if I should really be pushing through (via leves, etc) to lvl 70 and then working on the end game gear.

Knowing what you guys know now, what advice can you guys give me..?
