So.
Some interesting things were datamined from the 5.1 client, two new items.
Quest starting items.
Warlock only quest starting items.
The items in question are: http://ptr.wowdb.com/items/92426-sea...he-lost-legion
And: http://ptr.wowdb.com/items/92441-the-codex-of-xerrath
Now, this may seem like a regular class quest, perhaps they are bringing them back and only added warlock thus far, or warlock is the only class with items to start their class quest, who knows? I don't, it could be the case, but what makes me interested is the fact that The Codex of Xerrath is one of the items.
Warlocks who lurked during the MoP beta will recognize that name, and the old version of the codex is still on WoWhead (http://www.wowhead.com/spell=101508), it was long speculated that this book would give us green fire and the description changed all the time. It was not obtainable when MoP was released, but apparently, in 5.1 it is. And that description, "Corrupts all of your Warlock fire spells, infusing them with fel magic."
That's interesting. Real interesting.
What do you guys think?
