I dont see why people are complaining about atma progress, do it while you accomplish other things and then voila, it is no longer a chore and you get it in time. you have 3 weeks until you have the soldiery tomes to actually make the weapon useful (atma is ilvl 100 but holds no benefit). For an example, I got the time to do my hildibrand quest line which took me to upper la noscea, popped in a random fate, Boom got my atma of lion.

You are not supposed to grind your brains out on these fates instead of do other content, it is an over time activity. If you are complaining about wasting time you should reevaluate how you're spending it in a) a forum like this and b) any video game what so ever (if you're not getting paid)
