So I know Archimonde's vengeance sucks compared to KJC, but is there any fight where it could be used in ToT to good effect? On the same note, what kind of damage is reflected by it? For example, clever use of your gateway/portal and a lucky streak of not getting the thunderball chasing you in Jin'Rokh makes most of the fight very standstill. Would KJC reflect the damage from his thunderstorm?
P.S. My experiences are 10man Normal
