Ty so much for the reply!
Another question if you'll permit.... Do you happen to have a similar macro for 40 durability component recipes?
Why Observe in the macro?
Wouldn't surprise me if it gets nerfed by increasing cp cost from 21 to e.g. 25. Seems like they are trying to make some of the cross class skills less relevant, making it easier to get into endgame crafting. I'm not saying some of the cross-class skills are completely useless, they have uses but a lot are more situational now.
Unless I'm missing something, a 40 durability macro for non-leveling purposes seems pretty useless unless you plan on selling them. These 40 durability crafts are sub-mats for final crafts where this macro can HQ them without the need of HQ sub-mats.
I do have a 13 step macro but I don't know the exact stat requirements needed. I just know it requires really high stat.
