i sorta welcome that change..
you see, before i chained UA and Corr(same duration) but now that i no longer will use Corruption, i have to chain it together with SL, but that way it gets out of "sync",with this change basically, every 2 UA's i'll be using SL and they'll end at the same time, every 30 seconds
although it doesn't change much dps-wise, it makes managing DoTs a lot easier
i do hope the mana cost is reduced to reflect this change though
