The debuff that lands during this raid (Prisoners of Ankexfen) either has an incorrect description or an incorrect effect. The description says it reduces casting speed for beneficial spells, while the effect only applies to detrimental spells (and I confirmed this is what is happening while doing this event).
Sancus mentions the effect here: https://forums.daybreakgames.com/eq...soners-of-ankexfen.293329/page-2#post-4258919 The whole event takes a lot longer than it should, and it's not just the adds which have too many hitpoints. And being called by Navulta should really wipe your aggro, because being an offtank and getting called 4-6 times in a row is unfairly punishing.
Limiting aggro to single target fixes this, but does require more work on the tanks part. Bards can also climb the hate list with abilities to get chain called.
It is nice to have a longer event for a change, rather than 5 minutes and that's it. I agree with the offtanks getting called all the time.
Any word if the Snickering Doubt slow is supposed to totally negate all melee haste and spell haste? I saw a developer quote that said some of the slow was unintended but I'm not sure if it has been fixed now to what it should be.
