I doubt they'll add any new Chaotics, unless it comes as a SoF prize (don't forget to buy extra spins!). Since I'm no longer a member, I'm more concerned with the balance of the F2P rewards and Gravite equipment.
I just want the Gravite 2H to go back to crush. As it stands, F2P has no top-tier crush weapon. On a related note, I am glad that Gravite is finally summarily better in all 3 combat styles now; it bugged me with the previous system that the Gravite bow was underpowered compared to the sighted longbow (costing 1/4 as many tokens).
That said, I feel like the other non-Gravite equipment got hit with the Nerf-bat pretty hard. The Arcane blast necklace--a 15.5k token item requiring 50 magic to wear--lost its damage boost and instead got a crit boost that is 0.3% higher than the Amulet of magic (that's not an exaggeration, that's actually the difference). Additionally the Tome of frost--a 43k token item, higher than Gravite equipment--has lower stats than the Bat book and cannot be paired with any of the elemental staffs like it used to.
Long ago, the '90s Nicktoons lived together in harmony. Then, everything changed when the century turned. Only Avatar, the best of the 2000's Nicktoons, could save them. But when the channel needed it most, the show finished. Four years passed and Mike and Bryan created the new Avatar: Legend of Korra. And although the show itself is great, it has a long way to go before it can live up to The Last Airbender. But I believe Korra can save Nickelodeon.
