I like to craft armor and weapons for my Scholar as I level. Sure I can just level up on dumb FATEs and get quest gears but thanks to having good armor my dungeon progression has been very smooth. So far the worst dungeon for me was my first encounter with storymode Titan but I hear people having issues even before that. Usually it's because they are under geared. People say gear doesn't matter until 50 but in fact it does and it has made a difference in my story progress. But yea to each their own I guess, I can definitely see crafting being "pointless" if you like to run dungeons to farm for gear (which I do not.)
