How important is getting an extra 6 seconds on Devouring Plague so you can save mana on casting it less and use less GCD's over the fact that you will be getting less Improved Devouring Plague hits?
Anyone have the math on if it would be better to land 5 more IMP DP over casting 5 less?
I think I would rather have Vampiric Touch last 6 seconds longer. We will still end up saving mana and global cooldowns but won't have to waste the change of getting extra damage from imp. DP hits.
