9 pouches??? How many seals did you have??? Like, 4000?? I usually have 500-1000 and I might get 1 or 2 pouches if I'm lucky. Now, I agree that macrocosmic is fairly decent in dropping random stuff to sell, but let's face it. Unless you have a ridiculous amount of seals to burn, you aren't getting that many pouches each time the campaign comes around. Not unless you're super lucky and/or have multiple characters doing this.
Also, we need to remember that this takes Sacred Kindred Crests, and login points are the best way to get a lot of these. A returning player may be buying other things with their points, and they won't naturally have a surplus built up from years of play.
A few years ago I knew a 6-boxer whose main income loop was grinding escha mobs or easy apex to cap unity and then farming fights for sellables. Whenever macro campaign rolled around he'd usually have 20-30k seals to dump.
I couldn't imagine doing that much inventory management every day, but he seemed happy with it.
