I recently started playing WoW again after a few years, I'm not a big player (usually get over it after a couple of weeks, highest character is lvl60) but I noticed that all the skills and such have changed around (for the better I've found so far – kinda like it now).
I noticed at level 80 or so you can get a skill called Mastery with a extremely vague companion description saying something along the lines of "Allows you to benefit from the mastery rating".
Does anyone have a more clear explanation of what this does? Is it secretly awesome?
Best Answer
Mastery is a skill that was introduced in Cataclysm to provide some class specialization uniqueness: the reason it's so vague is because what it enhances is entirely dependent on what your spec is.
However, you can find out what mastery is currently doing for you in your current spec by hovering over the mastery rating in your character information panel, which you can access by pressing the C key (by default). That should tell you in broad terms how it's helping you.
You can also check out Wowpedia's Mastery chart for more detail.
