I remember using scrip tools in Heavensward just because I found it too difficult to craft 2/3 star gear with 1 star tools and I couldn't make better tools without better crafting gear. From my experience the difference between augmented scrip tools and overmelded crafted ones is minimal (mostly lacking a few CP from a meld) as the rest stats are pretty close. If like me in HW you struggle to craft better crafting/gathering gear then you could always just get the scrip tools needed (alchemist, weaver, leatherworker) to craft the gear and then make the rest of the tools
