From the Live Update Notes forum section in the post describing the anniversary event. New Styles, Feats and More! Unlock gear inspired by Lex Luthor’s Battlesuit. Discover two new collections for a title and new Bleed Auras. Collect two new Boss Statues and other new base items
Same, and there's still nothing on the broker (I have every collection in the game so the section is blank) :/
Apparently one collection can only be dropped by recently suspended players wich were unsuspended, granting the title: Naughty boy.
I've gotten a couple pieces of a new collection so far but only the two pieces. Mostly just a bunch of the old collections I've already collected most of the pieces of. Maybe they just have whack drop rates.
