Deathknight.info has just posted another batch of info from the Alpha forums, this time with Wryxian and Slorkuz talking about Shamans, Warriors, and Death Knights. Primarily, they focus on the tanking abilities of Death Knights and Warriors and delve into some possible improvements to the Shaman Enhancement tree in WoTLK, including possible new talents:

Shamans

Enhancement Shamans, says Wryxian, will probably see further review. It looks like a lot of the new Enhancement talents will see some changes as well:

• Weapon Specialization (which gives special abilities based on which weapon type the Shaman uses) will likely be removed
• Improved Shamanistic Rage (which made Shamans using SR immune to all movement impairing effects and stuns at 2 points) will also probably be removed.
• Wryxian mentioned a possible replacement for Weapon Specialization: Each melee critical hit would give a stacking buff that reduces cast time by 20% and lasts for 15 seconds. That would mean that at 5 stacks, you'd get a free instant cast spell.
• Feral Spirit, the 51 point enhancement ability that summons ghost wolves to aid the Shaman, may be getting a second look as well.

For Enhancement DPS, they hope that totems and shocks make up for the lack of melee abilities to keep it interesting, though they may consider a new melee move for Shamans as well. In addition, he promises new totem changes soon.

Read on for some juicy information on Warriors, Death Knights, and Blizzard's vision for tanking in WoTLK.
