Cygnuses are unavailable.

It would also be awesome if the rebirthed Cygnus Instructors got unique outfits too. I would love my Blaze Wizard to have an outfit like Oz. Also Irena outfit.. or Hawkeye outfit. would be awesome.

I've always thought that Cygnus Knights had a lot of potential.
Can you imagine a Blaze Wizard with aura's and DOT's? with fiery effects like a flaming teleport that burns enemies
A Night Walker that uses chains, bats, shadows, blood, all sorts of darkness related abilities, and a shadow based dragon blink, the first non-magic class to have one.
A Wind Archer that uses wind to have an extra jump like Jett and more aerial abilities like Mercedes, and with the ability to move around enemies by pushing and pulling using wind. They are already unique with a transform ability.
Thunder Breaker could have larger ranged punches, faster attacks that hit lots of times, a melee based Chain Lightning like ability, where the character jumps from enemy to enemy.

I came up with these ideas in just a few minutes, Nexon could easily make something of these characters

I think it's my greatest hope that Knights become less of re-skinned Adventurers and more of their own class. Of course, I'd also be fine if they either were replaced by Instructors or rebirthed into them.
