Can anyone explain the mastery buff hotfix?

[Deleted]

Arms
Mastery: Weapons Master’s effects have been increased by 57.1%.

Could anyone please explain what this means?
Do we get more dmg per mastery point now?
How much was it before and how much is it now, apparently?
Does this also mean that mastery is higher prio now than crit?

It means that both the base value of mastery and its scaling has been increased.
Its base value was 28% before the buff, and 50 points per 1% increase.

Now you're looking at 44% base value and ~35 points per 1% increase.
Second part I'm not sure of, need to test it out or somebody to confirm it.

It means you take your mastery % and multiply it by 1.571. This means all sources of mastery including the baseline 8 mastery points that every spec gets at level 80.

Is the hotfix active on your servers? On Ragnaros EU I still sit on the same amount of mastery and the % mastery hasn't increased. On armory it displays 56% but ingame only 36% so is it just a tooltip bug (stat panes work the same as tooltips needing a patch?) or has the hotfix just not been applied correctly?

Its active, the character sheet just doesn't reflect it.
