To answer some questions from previous posts:
Yes, Breeze was better than Clarity in the early levels.. it seems they've fixed this, but I'm not sure.
C3 (KEI), like all 50+ buffs, has a level restriction of 45+ on it, some higher, depending on the level of the buff. HOWEVER- There was a loophole. If it was a group buff, and a 44- was not targetted, then it'd affect anyone in the group, regardless of level. This has since been fixed.
