KoC blessing after big bang

I apologize if this has already been addressed, but I have been unable to find it. I have heard rumors that its a good idea to lvl your KoC because they have a 24 bonus at lvl 120 after the big bang patch. Any truth to this rumor?

The 24watt boost (instead of 12watt) is only for Ultimate Adventurers, which you have to make with your cygnus character.

All other chars on the same account, only get the normal 12watt blessing.
