Proto Ultima at Fanfest?

So I heard that Proto Ultima was battleable at the Fanfest. Sounds awesome. Too bad I missed the chance, since I didn't go. But it may look like we might battle him in a later patch (mayhap 3.5 most likely) like Odin for 2.5. Not sure if he's still gonna be 24 man in the patch though. What do you think?

Yeah, I'm at fanfest now, I did the fight. It was quite easy (but everyone had like best in slot gear) however, it was quite enjoyable!
