Were Cygnus Knights some sort of beta for future rebalancing?

It occurs to me that a few things that were changed between adventurers and Cygnus were similar to changes in later balance patches.

• Brandish coming down to third
  
• BW got Ifrit -> AMs got summon of their own element instead of inverse, Fire Strike is similar to FD/ID which was brought down to third job in Jump
  

These are the ones that came to mind, there might be others I'm forgetting.

Is this a co-incidence or was there some set of ideas going around in Nexon Korea's office?
