Hello!
Currently there is a heated forum post on my guild forum about this fight and dark intent, so I'm asking you warlocks this; Who would benefit the most from this buff? a fire mage or a shadowpriest? Note; Under the add phases.
The way I see it is that a fire mage gets the most off it under these 2 phases, more dots, faster redotting and so on. But I'm doing some research about this to be 100 % sure.
Anyone got some info about this?
