Patch 4.2 Changes

[Gaeios(Graxlos)]

WAAAAAAT!
Lots of healing changing stuff it seems.

A nice buff to crit ratings usefulness.

Classes: General

    All healing critical strikes now heal for 2 times a normal heal (+100%), up from 1.5 times a normal heal (+50%).

What looks like a buff to druid mastery.

Druid
Restoration
    Symbiosis (Mastery) has been removed and replaced with Harmony. Harmony increases direct healing by an additional 10%, and casting direct healing spells grants an additional 10% bonus to periodic healing for 10 seconds. Each point of mastery increases each bonus by an additional 1.25%. Healing Touch, Nourish, Swiftmend, and the initial heal from Regrowth are considered direct healing spells for the purposes of this Mastery. All other healing from druid spells is considered periodic.

Shamans watershield now makes them seem like oldschool paladins.

Restoration

    Improved Water Shield has been redesigned and renamed Resurgence. When Water Shield is active, Resurgence causes critical direct heals to restore mana (Resurgence rank 2 is roughly equal to 150% of the old Improved Water Shield value when a Healing Wave or Greater Healing Wave critically hits, and scaled down accordingly for faster or multi-target spells).

Y m8,
This is nots for shamy from blizz:

Shaman
Lightning Shield and Water Shield can no longer be dispelled.
Unleash Elements is now in the Nature school, and thus can no longer be used if a shaman's Nature school has been locked out.
Water Shield has had its internal cooldown reduced to 3.5 seconds, once again matching other shields. The amount of mana restored when Water Shield procs has been reduced by 50%.

Restoration
◦Improved Water Shield has been redesigned and renamed Resurgence.
