crafted gear between 51-59 and 61-69 is totally fine enough to play well.
and come on -.- since stormblood is out crafting is so easy that every blind clown can craft HQ. i didnt even had to change my craftinggear (lvl60 ilvl 190 with materia) untill 68. im sure it was no needed to craft 68 stuff i just made it cuz i was bored.
