While agree with your statement that good groups do make fights easier to DPS, it still makes me wonder why on your logs a SCH would need to cast Succor 22 times in A9S. Also with the large groups of mobs why a SCH would not cast 1 Bane. Visibly the WHM had the entire fight under control and due to the low gear level needed 2 Succor's for Acid Rain and Adlo for the Scrapline Tank Buster and possibly an Indom for the Faust AOE. The Fairy offered enough single target healing coupled with Rouse for when the Faust was out and Regens to sustain both Tanks.
Not to toot my own horn, but under near identical conditions I found the opportunity to perform 10X more damage back in Novemeber. This created a large reduction in the required TP for Melee Classes which in turn increased damage dealt directly to the boss and reduced fight time by 120 seconds.
Awesome well I'm glad you are progressing well. A11 is the first large hurdle for most groups. ACC is still nice on WHM for any opportunities where you can DPS since the other secondary stats don't really do a whole lot in comparison.
