Patch 4.1 on Live Servers this Week

"We will be extending maintenance for all realms for 1 hour 30 minutes and anticipate they will be available for play at 12:30 PDT. We will provide additional updates as necessary". This of course was after the already planned downtime for the patch.

• Dungeon Call To Arms Interface/Mechanics.
• New Valor Points and Daily Dungeons gains.
• New Dungeons - Zul'aman and Zul'gurb (Heroic 5-Man).
• Heirloom Tanking Items.
• Maelstrom Crystals and Honor/Justice conversion.
• Guild Challenges.
• New Archaeology Rewards.
• Poseidus and Reins of Poseidus.
• Cooking and Fishing Daily Quests.

Nothing really stands out to me except for the Warlock class changes. I am still not a fan of running old content as "new" content such as ZA/ZG, and I never liked ZG to begin with.

On another note, our guild killed Cho'Gall for the second time after many bloody attempts. He dropped a Vanquisher token, Caster ring and a 2-handed Axe. The ring is nice, but sad to say it's not really an upgrade.

All the new features/changes are here and here
