Elemental mastery changed on PTR

[Stealthy]

It's a nerf for PvP, since it reduces our burst.

In PvP, you normally pull out EM + FS/LvB when you need an instant (almost) guaranteed kill. However for the next 8 secs while LvB is on cooldown , you'll be relying on your next biggest nuke - LB/CL + FrS. Since none of these spells have a guaranteed crit, 15% crit >>>>> 15% haste in this situation. Getting your spells off 0.2-0.3 secs faster doesn't compare to 15% higher chance for killing a target outright.

Cheers,
