As many of you know the next major content patch will include some very exciting things, such as Ulduar, a new epic raid dungeon, a wealth of new items, and much more. We thought players would especially enjoy reading just a few of the class changes we're currently planning. Please keep in mind, that this list is not at all comprehensive, and more importantly subject to change.

• Hunger for Blood – instead of a self-buff, this ability can only be used when there is a bleed effect on the target. However, it has no stacks and grants a 15% damage bonus.
• Adrenaline Rush – the cooldown on this ability has been lowered.
• Lightning Reflexes – reduced to 3 ranks. In addition to 2/4/6% dodge, this talent now also grants 4/7/10% passive melee haste.
• Killing Spree – while this ability is active, the rogue does 20% additional damage.
• Savage Combat – now causes 2/4% physical damage done.
• Mace Specialization – this talent now grants haste in addition to armor penetration.
