Shaman (Skills List / Talent + Glyph Calc.)
Elemental Shaman changes (Source)
Hopefully this won't get buried here. Here is what we are thinking about to try on the PTR for Elemental:

Elemental Oath -- In addition to existing effects, now increases spell damage done by the Shaman by 5/10% while Elemental Focus Clearcasting is active.
Elemental Mastery -- Overhauled. Now increases the Shaman’s critical strike chance by 20% for 30 seconds. Cooldown remains 3 minutes. We recognize this might be a slight nerf in certain PvP situations where players relied on the shaman to nuke an injured person to death. Still, I'm betting most shamans will prefer the new design.
Glyph of Lightning Bolt -- No longer affects cost. Now increases damage by 4%

What do you think? The Elemental Oath thing is obviously a buff to make crit more valuable to shaman...
But the Elemental Mastery change is disastrous for pvp IMO.. that stuff will get mass dispelled/purged/whatever within seconds along with our lovely heroism with a 5 minute lockout.

Big meh for my part. PvE crap that will only be usable against clueless teams in pvp. Or so it seems at least. During season 4, I was lucky to have heroism on me for more than 5-10 seconds.


Edit: It seems to me that Blizzard is so busy trying to balance classes' raid performance based upon the latest Elitist Jerks exploits, that they forgot about arena and how much more important arena balance is for the game experience, than some cooperative 10-man mini game that isn't even hard to begin with. Bleh.
