My 10man put in only ~30minutes on Elegon last night and I was having issues as frost.
The most frustrating thing is that, because Elegon is floating just above the ground, my water elemental's freeze does not hit him and I lose my FoF proc from that, unless I wait for the add(protector) to spawn, which makes me wait to cast freeze for 5-10seconds.
DPS-wise, I've been 2nd-highest damage on the first four bosses, but near the bottom on this fight.
It could be that I'm not handling my Touch of the Titans buff properly. I am typically only going up to 6-8 stacks before dropping my buff to put less strain on the healers.
I'm running with Invocation, but I'm thinking incanter's might be a better choice for this boss.
I've also been using frost bomb, although I'm thinking about switching to another bomb that's instant cast so that I can refresh it while running out to reset my stacks.
Any mages who have downed Elegon have any advice for me?
