A.) Sonics should be maxed to begin with regardless of whether or not you go down the harmonization line.
B.) There are only 4 options in the inspirations line that you should even consider maxing. ( Jcap, Aria, and the two wards). The rest of them essentially useless.
C.) Most mobs in the game do NOT use CA's. Making the end line in demoralizers useless.
D.) The benefit of having 10% longer jcaps/potms/poms/dispatch/cob/<insert and other temp buffs/debuffs that are nice> AND reducing the duration of dots/hots (more damage or heals in a less amount of time) is overall better for your raid and group than the demoralizers line will ever be.
E.) This question was already asked in the Troub AA thread and answered. Search function ftw. http://www.eq2flames.com/troubadors/...-thread-9.html
