I predicted it for the expansion 3 years ago, but it finally came to pass. SOE is adding a 25th class to the game, the Beastlord.
There were some other high level items announced at the Fan Faire keynote.
The next expansion for EQ2 will be the Age of Discovery. It will have more AA points to be earned, new zones, a build your own dungeon feature, along with the new class. The release target is November 2011.
I am sure details about the new class will be forthcoming.
Personally, I hope they went with the idea of being able to tame your own pet. I hate to have people say SOE is copying WoW, but the whole pet taming really made the hunter class in WoW.
From the update over at EQ2Wire (subject to change):
Beastlords are Scouts
Melee DPS class, on par with other top-tier DPS
Pet class on Steroids
Should always use a Warder to be effective
Can collect and use many different types of Warders
Different Warders have different abilities, hotbars, AA lines
More utility, damage, combat
Use stances to affect what ailities become important
And from Massively:
As for details on the class, he stressed that things are still being worked out, and are subject to change. It will be available with the expansion pack, and is a scout class with leather armor who uses brawler weapons. But what sets the Beastlord apart is his warder pet, which has its own AA tree and special abilities. The Beastlord develops a rapport with his pet through the use of particular combat abilities, and as he builds up that power, he and his warder are able to use special, more powerful abilities. It’s a very active class, and it requires people to participate more in the battles than with some of the other classes.
