Race Crossovers
The best Horde race changes as a fight gets longer: an on-use racial wins short kills, a passive one wins long ones. This page finds the length, to the second, where each spec's best race changes hands. For the winner and runners-up at one length, use the Horde Race Picker.
Where the best race changes
A lead under about 0.15% is not counted as a crossover.
