1.this type of content is clearly intended to keep players paying their subscription until next update and I have no issues with this, but we are going towards other major update so they could have at least increased the drop rate.
2.we are not against grinding! It's the idea that lies behind that creates a problem!
Is this too hard to understand?
EFFORT --> REWARD is the normal path, Atma is: EFFORT (and a big one: endless number of FATE) --MAYBE -->REWARD.
It has nothing to do with grinding, farming or time: you have no guarantees that in - say - 1 year you will get your ATMA Weapon.
Farming mitho and completing dungeon / hard boss would be ok: it would take time, but I'd slowly reaching my objective.
I can understand you want to feel special and I'd gladly help you to find other reasons to feel so, but please accept that reality: at the moment this system is just sick. People spending a whole day doing fates hoping to drop an atma and getting 0 after 24 hours is sick!
