Back at Blizzcon, some improvements were previewed for Enhancement shammies that were going to go in "a future patch". It has become apparent as things progress that this patch is probably going to be 2.3, and now we have confirmation of that from Eyonix. Specifically, the details he confirmed for patch 2.3 are as follows:
- Shamanistic rage will also reduces all damage taken by 30% for the duration of the ability (30 seconds), in addition to its current effect
- Spirit Weapons will also reduce melee threat by a total of 30% rather than 15% (source)
- There will be changes that benfefit [sic] the elemental and restoration shaman as well. And yes, more enchancement improvements are absolutely going into patch 2.3. (source)
- Yes, all shaman will be able to equip 2-handed axes and maces (proper training required of course), without having to spend a talent. In it's place, a seemingly solid replacement talent called elemental focus. Basically, what it offers is this -- after landing a melee critical strike, you'll enter a "focused state". The focused state will reduce the mana cost of your next shock spell by 60%. (source)
There is some confusion over whether Spirit Weapons' threat reduction affects yellow damage; Eyonix reports that extensive internal testing shows that it affects white damage and Stormstrike and Windfury procs. He also promises to drop in on a thread discussing Elemental improvements, so keep an eye out for that.
