Seems flawed they're shooting nerfs that are unexplained behind their reasoning. Sure, some proper nerfs were okay (lol fish hooks to avoid profit saving on synthesis), but why the synthesis & tools downgraded on specific crafts? Some stuff doesn't make sense but no one seems to complain. Why? What are we trying to improve while the other gets downgraded? It's the very same thing we observed with the mega update in November, but in return a price was realized that made players step up and voiced how upset the SP changed ruining the "causality" of partying.
The bold synthesis nerf came as a result of the buff to success rates for standard synthesis. SE doesn't want
HQ gear/higher quantity of mats flooding the market so they originally tuned the system to produce a higher rate of failure and when the players pointed out that it made crafting an irritating chore instead of a fun little mini-game, they tweaked it a bit.
Personally, I'd rather see them take it the next step and set explicit thresholds for HQ results. Over 100 quality? Guaranteed HQ1. 200 quality? HQ2. HQ3 from 300+ quality and then tweak synthesis results so that they're in line with the kinds of HQ results SE wants to see.
Regardless of what I'd like for them to do, they made the changes that they did for a pretty obvious reason (specifically in regards to quality gains from Bold synthesis). I'm sure that with the addition of all the new tools they felt equally justified in nerfing some existing tools as well.
Nobody likes being nerfed, but it's not always for the ubiquitous "no good reason".
