OK im pretty sure this was asked before but my search came out empty, i wanna know what to focus on when gearing up (basically for my GSM) i noticed all the high level gear has Magic Craftsmanship and the normal one is margined out, does this mean i should focus more on it (Mg. Crft.)?

I read somewhere that Craftsmanship affects jobs which rely on physical attributes i.e. GSM main-hand uses DEX and thus more Craftsmanship points equals easier synths and Magic Craftsmanship affects jobs which, apparently, rely on magic attributes i.e. ALC main-hand uses INT etc. etc., im not sure how true/accurate this is since SE have given little to no explanation on these two attributes..

i'm currently gearing up to focus on Craftsmanship but i cannot switch to higher level gear because they're all moving towards Mg. Crft. and i dont know if im doing things right or not , this issue has been bugging me for a while now and i havent found any solution so far

does anybody have anything to add here and probably help in clearing the fog?
