I haven't tried Vorkath yet and I probably should as I'm almost 2k total on my iron! But Sarachnis I've gone to a few times, another Raid is coming out early next year (January, I believe) so that'll be sweet.
I like KBD, Kraken & Cerb (when cerby drops me something
) I'm looking forward to more in the future myself! Skilling wise, Zalcano is awesome! If you haven't got to Zalcano yet I'd recommend doing Song of the Elves!
