First off, i'm a fire mage with 496 ilvl - Slightly higher than the average of people attempting this.
So after getting lucky getting my invite on Wednesday (Only took 15 rare kills, thank god) I managed to make my way quickly through to the max rank without much trouble. I am currently 3/4 on rank 8 with only Disruptron left.
I am having serious problems with this fight. Avoiding most of the damage is fine, however I am having problems beating the enrage for two reasons.
I need to move a lot, I could use scorch but then I lose a big part of my dps on combust (Unless I get very lucky, which I don't want to rely on with 30 minute queues).
Second of all, the "soft enrage" mechanic appears at 25%. this makes all 4 canons in the corner and the totem in the middle shoot the discs out at the same time. I can't see any way of avoiding this without pure luck or a safe spot (Which wouldn't really work, since you need to jump over the lasers anyway.
Has anyone actually beat this yet? I've had around 80 tries on this in the past 2 days and I can't help feeling that i'm missing something.
Edit: Also, if anyone has questions about previous bosses feel free to ask in this thread.
