More on the Rolling Corruption Nerf - The Warlocks Den - WoW Warlock Discussions

If it had been a matter of skilled warlocks able to focus all of their haste cooldowns at once for a small or medium dps increase, then yeah, maybe that would have been cool. The problem was it was a very serious increase, especially in a world with Bloodlust. The damage was just out of line. We considered somehow nerfing the benefit haste gave, but that would defeat the whole point of the glyph in the first place. Other options would have been to nerf Everlasting Affliction or change the haste glyph to affect Unstable Affliction instead. Both of those seemed like bad choices compared to just letting the refresh not keep rewarding you for the initial burst of haste.

I agree with the person who said the direction was to make haste a more attractive stat, not to develop a new play style about blowing a ton of haste cooldowns at once and then [trivially] refreshing the dot forever.

Aca se puede hacer haste rolling, everlasting affliction refresca el corruption con todos los valores de haste originales (pociones de speed, heroism/bloodlust, procs de haste)
