In addition to the big change of Nethers not being BoP anymore, some other changes were pushed to the PTR tonight:

Commendation of Kael'thas has had its dodge rating bonus reduced from 380 to 152
Five epic trinket jewelcrafting recipes have been added, all with passive benefits and on use effects. See this MMO-Champion screenshot for materials.

Crimson Serpent: +33 Int, + 49 Stam, use: +150 damage/healing for 20 sec (2 min cooldown)

Empyrean Tortoise: +42 def rating, use: +165 dodge rating for 20 sec (2 min cooldown)

Shadowsong Panther: effective stealth level increased by one, +80 attack power, use: +320 attack power for 15 sec (2 min cooldown)

Khorium Boar: +84 attack power, use: summon the Khorium Boar to fight for you for 30 sec (5 min cooldown)
Seaspray Albatross: +18 mp5, use: restores 900 mana over 12 sec (3 min cooldown)
New gem cut: Regal Nightseye, +4 dodge rating, +6 stam, matches red or blue
Warlocks' Drain Mana buffed by 50%; top rank now drains 300 mana per second (was 200)
Paladins' Holy Shock damage buffed by about 35%, healing buffed by about 75%. Top rank now deals 721-779 damage or heals for 931-987 (was 530-574 damage or 530-574 healing).
That's a lot of changes. And now that I look at those numbers, those are big shifts for Drain Mana and Holy Shock. Is anyone now reconsidering those spells? Do you think those buffs will last through testing?
