Oh I don't really think it's a bad design strategy, if anything I thinks it's a really smart choice to make atmas also drop from the fates of the different zones, my only issue is that within OC verdigris only drops from one CE, had there been two i would not have any issue because while RNG is a boring kind of grind I don't really have an issue with it personally, especially if it's alongside progressing on other things, which is what this design is doing.
Yes, and it's sad to say, that not every zone can be living memory (or heritage found, neither of them trigger the sync) but it's just what I must do... and most likely alone as those I did OC with had better luck getting verdigris and I don't want to burden them with fates since they are all really vocal about disliking that, I find fates boring myself but I'll manage, I only really whined about kozama because the fate sync is a personal gripe of mine hehe.
So yeah as you said I've correctly identified what I need and my plan is to go kozama once i get that azurite, if I'm lucky a verdigris might also drop before then but the odds are kinda against me with there only being one CE in the area, which again is my only issue, I also want to specify that my "nightmare chore" comment was only for inside OC as focusing on RNG often makes it tedious.
I did want to focus on this bit, as it confused me some.
I'm guessing you meant "get the azurite then go kozama" vs "stay progressing in OC but slower verdigris" in which case i want to highlight that i will progress something regardless on if i stay in OC or not, once more my main issue was within OC only.
Not sure what epic progression is but i guess you meant relic? as for gold/silver(?) grinds unless atma also drops from random mobs I'm not sure why you mentioned it (unless again epic means relic and you meant OC progress vs relic progress) also really sorry if this is a lot to read.^^;
