Oho, patch 6.58 removes the weekly limit on Thaleia coins! Time for me to finish my last three pieces of Augmented Credendum gear for Sage. After that only two projects will remain before I have everything done that I want before Dawntrail: maxing out my crafter/gatherer scrips (fairly easy) and finishing retraining my retainers (slow but only takes a few minutes a day).
