I bet it's not about crafting stuff, but element from dust
For me it's both but by far not only Element crafting (right now I run exactly zero Gachas). You all know that there are way faster ways to get to Element then Dust from Gacha's. Sure Gachas are the least work once they are setup you just have to be "online and ingame" to get some dust coming in. But if you would spend the same time "waiting on your Gachas" to hunt for Element veins on extinction for example you would get way more Element in the samt time spend ingame.
If Dust would be the only reason why people ask for a solution to the mindwipe downsides they could just keep asking for changing the current rule that you can't transfer Element between servers instead.
