There is a litter more changes for Shaman, Rogue and Priest in upcoming patch 3.1, those are important if you are Shaman, Rogue or Priest player. Mostly, for Shaman, mana Spring and Healing Spring totems combined, along with Poison Cleansing and Disease Cleansing combined. Shaman's Spirit Weapons now reduces all threat and Chain Lightning now hits 4 targets. Priest's Divine Spirit is now a base ability of all Priests. Priest's Power Word: Barrier, a new Disc Priest talent that acts like a Power Word: Shield for the entire group. Rogue's Killing Spree increases damage an additional 20% and Mace Spec now additionally increases haste.
Shaman:
Chain Lightning jumps to 4 targets but does less damage. We wanted to make the distinction between Lightning Bolt and Chain Lightning clearer.
Storm, Earth and Fire increases all damage done by Flame Shock, not just periodic damage.
Spirit Weapons reduces all threat, not just melee threat.
Unleashed Rage reduced to 2 ranks, now also increases your critical strike chance with melee attacks by 1/2%.
Totem streamlining: The Mana Spring and Healing Stream Totems have been combined. The Disease Cleansing and Poison Cleansing Totems have been combined. We are working on giving Enhancement and Elemental more PvP utility.
So chain lightning is going to always jump to 4 targets now but do less damage. Hopefully the glyph will reduce its mana cost now or possibly even the cooldown more since it originally gives us the 4 target boost and the damage nerf. This is an alright change, nothing to write home about but the added target is going to be nice if it's spamable for AOE fights.
Spirit weapons reducing threat from all attacks including spells cast is great, why the hell did it take them this long to do this? Unleashed rage is awesome now with the freed up talent points and the bonus 2% crit.
The merging of disease and poison cleansing is going to do wonders for healing in raids especially in Naxx where you often get both applied. Same for mana spring and healing stream as it will cause a general regeneration across the board. We can just imagine in arenas now how Rogue and Death Knight groups won't be obliterating groups with Shaman in it
Rogue:
Hunger for Blood–instead of a self-buff, Hunger of Blood can only be used when there is a bleed effect on the target. However, it has no stacks and grants a 15% damage bonus. Adrenaline Rush – the cooldown on this ability has been lowered.
Lightning Reflexes reduced to 3 ranks. In addition to 2/4/6% dodge, this talent now also grants 4/7/10% passive melee haste.
Killing Spree–while this ability is active, the Rogue does 20% additional damage.
Savage Combat now causes 2/4% physical damage done.
Mace Specialization grants haste in addition to armor penetration.
Priest:
Divine Spirit is now core ability available to all Priests.
Discipline has access to a new talent, Power Word: Barrier. (Think of it as Power Word: Shield for your whole group).
Several area of effect (AOE) heal spells have been improved: Prayer of Healing can be cast on any groups in your raid party. Holy Nova's mana cost has been reduced. Circle of Healing now heals for more.
Shadow priest PvP survivability has been improved: Shadow Form now reduces magic as well as physical damage. Dispersion now removes snares.
Penance can now be targeted on the priest.
Serendipity reduces the cast time of Greater Heal and Prayer of Healing when Binding Heal or Flash Heal is cast. We are also working to give Holy additional PvP utility.
