Simple, because it nullifies the 'effort' and the point of having the crafted counterpart in the first place and the melding required therein regardless of whether you can or cannot purchase them, the only thing I am defending here is the very fact you would be eliminating the tools very early on regardless of how these tools are obtained is frankly irrelevant since people are still required to meet the stats to craft them and similarly were required to farm for them.
If you think that the crafter relics for 90% of their entire progression weren't content-less fast food-esque level of stuff then you're deluding yourself. Let's look at it, shall we... Crafter relics have you grinding for scrips - Guess what else asks you to do this? the tradeable Indagator tool. If you view the relic thus far, and even arguably through 95% of Shadowbringers as substantial content with a worthwhile grind then you're kidding yourself.
As per my initial post, regardless of whether the crafted tools are 5 item level lower or whether the relic would turn out 5 item level higher, there is very little or no measurable benefit in doing so, seeing as how the stats with crafting work.
Unless those relics provide meaningful change to your rotation and/or your consumption usage, then for all intents and purposes regardless of whether they are 620, or 625 then they provide absolutely no tangible benefit. - This was the case for 99% of situations involving the skysteel tools.
The relics are effortless gear for crafting. if you think that a temporal equal-to alternative existing on the marketboard changes this fact then you're kidding yourself. doing 50 crafts is not a grind. If you want these relics to be measurably better on same patch, then frankly people should be required to undertake a grind equal to, if not worse than the resplendent on a 1:1 basis.
Now with all due respect, if you're arguing that a relic that has required 50 crafts amounting to the equivalent of less than a day's work to get all relics warrants a tool that exceeds that of pentamelding in a measurable sense then you're advocating for a pretty effortless grind still. These haven't even asked for expert recipes, nor recipes exceeding the crafted variant in difficulty, and you're complaining about the tools not being better?
These functional macros generated by AI are still subpar and inefficient when compared to people that actually know how to make a macro.
