Completly agree!
the randomness of crafting is so agrivating!
I do my crafting leves at every possibilty but because of the massive required sp per level, I have to sink gil into my craft,
It is so disheartening to fail after completing 5 synths with plenty of durability left then fail at bearly 50%, wasting time and gil!

this needs to be adressed just as urgently as the battle system, because of the time people put into leveling crafts.
