Patch 3.08 will bring the following Enhancement Shaman changes:

• Static Shock has been swapped with Mental Quickness and moved to Tier 8.
• Mental Quickness has been swapped with Static Shock and moved to Tier 9.
• Mental Quickness PTR changes have been reverted and now properly scales from attack power again, increases your spell power by an amount equal to 10/20/30% of your attack power.

Glyph of Windfury Weapon changed from:

• The attack power bonus on the additional attacks granted by Windfury Weapon is increased by 40%.

to

• Increases the chance per swing for Windfury Weapon to trigger by 5%.

Since we are all wondering what this change will mean for us I decided to do an approximately 1 hour long fight, only autoattacks on a target dummy on Live and on PTR, using the same gear and only the same totems.

Live: http://wowwebstats.com/altn2rmj45rea?a=xade4a3

Swing (Physical) 4056153 damage 62 %
Windfury Attack (Physical) 1391211 damage 21 %
Flametongue Attack (Fire) 1059910 damage 16 %

Number of Windfury Attacks: 683

PTR: http://wowwebstats.com/skoeu4gujfqza?a=xb4662e

Swing (Physical) 3783135 damage 58 %
Windfury Attack (Physical) 1732833 damage 27 %
Flametongue Attack (Fire) 985742 damage 15 %

Number of Windfury Attacks: 854

As you can see the percentage of Windfury attacks has significantly increased. While on live realms Windfury procced only 683 times, the number of proccs raised to 854 on PTR with 3.08.
The overall damage was a bit lower, due to a higher missrate. This resulted in less normal melee damage and less Flame Tongue damage.

Another thing I noticed was the damage of Windfury Attacks:

Live Windfury Damage:

Avgerage hit: 1556; Max hit: 1850
Average crit: 3203; Max crit: 3788

PTR Windfury Damage:

Average hit: 1564; Max hit: 1906
Avgerage crit: 3212; Max crit: 3815

The glyph should lower the damage, but apparently the damage is exactly the same. This implies that the WF Glyph is currently not working on live Servers.

If these changes come live we can actually look forward to them.

Here are some more undocumented changes and hopefully incoming fixes:

• Spirit Wolves
  “Just wanted to post a thanks and an update to the Shaman community that Feral Spirit is indeed scaling now with Attack Power and Crit in the PTR.”
  The patch notes tend to record larger changes to the way things work. We fix literally hundreds of bugs that don’t get incorporated into the patch notes. This one was just a bug.

• Spirit Walk
  Spirit Walk is supposed to break roots and snares on the wolves and the shaman. I know we’ve had a bug on that. I’ll need to do some research to know if it’s fixed. (Source)
• Mental Quickness
  Shaman talent Mental Quickness is currently bugged, it corretly works for spell damage (the tool tipway of 30% ap to sp conversion), but for bonus healing it is still calculating from 70% of the shaman’s agility (the old build’s model).
  We’ll look at it. Thanks.
