MuscleWizard pretty much summed up my thoughts of the Chaos build. I wouldn't recommend Thorns+FC first build for anyone. A single point in Thorns gives 32% stance, which is great for just one SP and it should be enough until you are done with Blade Fury.
I also would recommend 1 point into Mirrored Target early for the dodge, and maxing it later in stead of MW. In training parties, everyone and their mom has MW of some sort so adding points into soloing purposes isn't that important IMO. Aside of just the dodge, MT gives a big big boost in both defenses, and the Puppet feature is handy for doing bosses like BGA.
