So theres three things I will talk about, but only one answer i want to know.
Glyph of Quick Decay - makes corruption tick faster based on haste pretty much
Eradication - your corruption has a 6% chance to increase casting speed by 20%
Everlasting affliction - Your Corruption and Unstable Affliction spells gain an additional 5% of your bonus spell damage, and your Drain Life, Drain Soul, Shadow Bolt, and Haunt spells have a 100% chance to reset the duration of your Corruption spell on the target.
SOOOOO, what i want to know is if...
I have quick decay and put a corruption on a target, then halfway through Eradication procs and now i have 20% cast speed do I have to cast another or would the everlasting affliction corruption reset automatically adjust with the 20% haste.
if that's confusing just explain some other way how those three talent/glyph work together. they seem pretty good.
