Except you're wrong.

Rebellion is the only "all-rounder" weapon, equal offense, defense, mobility and combos.

Agni and Rudra are quick offense but lack defense, specials have an after-pause of at least a second, which is far too long, especially Crossed Swords or Jet Stream, or the insane pause during and after Million Slash

Cerberus is quick, but lacks Air Hike, so you have far less mobility.

It's fine if it's what you prefer, but don't act like what you prefer is the only "ultimate" set of weapons, because every other is just as effective.

Nevan is strong at long-range, has some of the best crowd control moves and is by far the most defensive weapon in the game due to the stun effects of it's moves, just most people pass it by because they either can't use it or don't even try because of OMGDUELSORRDDSS!!!111
