WHY?

You've hit that wall known as Level 60, at least once if not multiple times, as WoW has been voted "Easiest MMO to Cap Out Ever"; Blizzard's new level cap of 70 will at least give you something higher to shoot for.

They're not just upgrading spells and skills (like Conjure Water rank 32, or Kidney Shot rank 19); they're adding brand-new ones, as well as additional tiers in the talent trees.

The socketed item phenomenon that was sort of "coined" by Diablo will be implemented and Jewelcrafting added to the tradesperson skill set.

Alliance players will enjoy playing as Draenei, and the new Blood Elf race gives the Horde faction its first exercise in what humans perceive as sex appeal (even though those Troll females are pretty cute).

If you're bored with the same old continents and dungeons -- which you probably are -- Burning Crusade adds the planet of Outland, formerly Draenor, around which Level 70 characters can fly on Nether Dragon mounts.

WHY NOT?

You can't fight on your Nether Dragon, nor use it outside of Outland, and it's slower than the current flying contingent of Griffons and Bats.

They're not planning to add new classes at this juncture, nor will the "hero class" be ready to launch.

Those of you who've spent the last several hundred game hours getting those epic armor sets and Arathi stuff might be disappointed that they won't be the end-all and be-all anymore.

And will the current zones all of a sudden become deserted when people flock to the new areas? (Have you been to the n00b zones in EverQuest in the past thousand years? The NPCs are there, but they're awfully lonely.)

"The Draenei are one of the three primary races native to Draenor (the others being the Orcs and the Ogres). They once populated the planet heavily, but were slaughtered by the Orcs shortly after their corruption by the Warlock Gul'dan. A small number of Draenei survived, using a recessive cloaking ability. Severely mutated in the destruction of Draenor, they were thought to be extinct, but Illidan and his forces discovered and liberated one of the last surviving Draenei villages among the wastes of what is now known as Outland. The Draenei are known for being stealthy spies and assassins as their warriors can Shadowmeld at all times of day, even while moving. They are currently ruled by Akama, the Elder Sage, and are allied with Illidan's Naga and Blood Elves. The Draenei are consumed by an unquenchable bloodlust whenever they know Orcs are near. A few Draenei were led through the portal by a few unknown leaders with the hopes of finding a new life, and have settled in The Swamps Of Sorrow. Unfortunately, most of them were driven mad due to homesickness, and attack all on sight. There are a few, led by Mag
toor, that remember their noble roots and survive on in the swamp separate of their mad brothers. The mad Draenei are called "The Lost Ones" in memory of their old homeworld. They are a likely candidate for the new Alliance race to be added in the Burning Crusade Expansion."
