Feb 22nd 2012 11:45PM Reading "Rise of the Horde" would be good. The statement you quoted is correct but they did not drink the blood until they attacked Shattrath. They had already destroyed the Black Temple and another place that I cannot remember the name.
The power of switching to warlocks also predated their first attacks on the Dranaei. They increased their numbers to fight by using fel energy to age the children very quickly.
Finally, Pyromelter, the first few attacks were not predicted by the Dranaei. The first attack was unknown by them and it wiped out a good bit. The attack on what was to become the Black Temple was also a surprise. However the attack on Shat was known about hence the drinking of Mannoroth's blood.
