The gobbie food issue isn't that you get gobbie food it's that you it wont reroll for one you already have. And the uses for multiples of the same are very limited to say the least. Recursing old stuff is a lot of effort for nqs that I'm already having hard time selling for 20-100k lol and multiple of the same 119 set but on different paths can be quite costly unless you sticking to nqs
Also I call bs on 2.5 full escha sets unless by "this campaign" you mean all the abj dial campaigns so far. Not even counting having uneven amounts of repeats that would be 137 of them. Even assuming a very generous distribution of 1 escha for every 4 checks (I'm at more like 5-10% really but rng 25% seems reasonable for some) and even with 10 characters to look on would take a couple of months to get that many. And hell checking with 17 characters over all the campaigns combined I've not seen a single escha body forget 27 lol
