You don't suddenly lose credibility on an opinion simply because I got it faster then you did or others. I agree the Atma is the WORST part of this quest chain I fully agree as well their should be a NON RNG option for it.
I can't disregard the fact I was lucky enough to get my atmas fairly quickly but I also can say I busted my ass for hours on end farming them. Several of my friends as well as myself farmed them up from 0 within 3-4 days as well after the Nexus patch.
You have a mix of several people saying they've farmed their atmas for days on end, when there are also some who claim the same and they maybe put an hr or less into it. These both different types of people shouldn't count towards the claim atma has terrible drop rates. It's not great but it can drop if you persevere at it, but then again most people on this game aren't THAT dedicated to one thing so it seems like endless grind and maybe to those who put extensive hrs into it, it rightly is 'endless'.
They only need to add something that's progressional for atma and it will be solid enough to be ok. Grind for one, with a chance of getting one by luck. Atmas shouldn't be given out like cake either. So I'm rather skeptical for a drop rate increase. Exactly how much would be fair? You shouldn't be allowed to get all your atma in less then an hr either.
