Feel excited about spending the extra points in the off trees, and this is wow gold.
The real confusion with the blood tree probably comes with the incredible amount of focus placed on Blood Boil. Blizzard has said that they plan to de- emphasize AoE fights in Cataclysm in favor of the class model of crowd control. It seems strange, then, that they have dedicated so many talent points to optimizing blood's AoE ability. We start with Hemorrhagic Fever, which causes Blood Boil to reduce physical damage done by all targets by 10% for 30 seconds. It seems pretty likely that this will become sort of a mandatory debuff for blood tanks to put up. But since it's attached to a damaging AoE ability, that also means that it will break crowd control whenever you use it, don't hesitate to buy cheap wow gold for WoW. The fun isn't over there, no. The Blood Boil portion of Might of Mograine has been split off into a second talent called Crimson Scourge, so you now have three more points you need to spend, and may want to spend if you need to be recasting Blood Boil often to keep an important debuff up. Luckily, they're making a new talent, Blood Swarm, which gives you a free Blood Boil whenever you use Plague Strike, for five points. That's 10 points dedicated solely to making Blood Boil a power and viable AoE and debuffing tool.In short, it's obvious the blood tree needs at least a few passes before it's completely ready for prime time. There are some interesting ideas here, but Blizzard really needs to stop being so schizophrenic about their intentions for AoE fights.
