As an alchemist, potentially having to do 45+ synths of something like Echo Drops to make myself a stack to sell is not my idea of fun. That's at least a half hour of straight synthing for presumably meager profit as the need to buy 99 will be far less frequent than a few stacks of 12 if you know you'll be fighting some silence-happy critters. Yield increases should also accompany such an update.

Otherwise, stacking ore, lumber, all fish, empyrean items, clusters (with an option to cluster crystals from 12), and some medicines is all good. I'd levy changing the Warp Cudgel cooldown timer to 15s instead of tweaking scrolls, though. Cudgels for retrace wouldn't be bad, either. Oh, and tweak the various synergy warp earrings to lower timers, too.
