Bumping this over to Under Consideration, I do have a question: how many Passes are you guys actually using/lending? What "size" of "mega pass" would be useful?

Speaking for myself, I have 150ish passes. I have loaned anywhere from 5-99, but honestly even packing them together as 10 is an improvement. I personally use all of mine typically and if I have loaned some I use all of them as well. The most I have used is around 300 total, but I'm ordering swarm eggs for my hunts. If I was ordering a more expensive egg I wouldn't use nearly as many 😅

I currently have 14 and I'm looking to get one or two more on the next Elta day, but I know people with 50 or more, and I've borrowed up to 76 before ^^

I got 270 passes that I lend at any given time to friends who need them. That said I typically loan out a hundred at a time.

I have 250 and want to get to 500 at one point when I collect enough GP. I keep the supplier eggs or when I get pkrs and thus can grab eggs without scouring the shelter. I've lent out 200 at a time to people. I think 10, 50, and possibly 100 Mega Passes would be most useful in regards to lending.

I have 547 and I occasionally lend them all out at times

I have 156 supplier passes and I was planning of stocking up to around 200 passes for legendary hunts. Though gonna wait now and see what will come out of this suggestion.

I've worked my way up to 100, mostly just use them for type race prep.

I've got 60 myself ^^ I'm hoping eventually, or maybe during this overhaul, an ability to influence the nature of supplier eggs is added, and then I may be able to use them more, but for now I mostly use them to supplement my adopts when hunting low-ehp/swarm mons, or when dealing with a low percentage breeding pair, ex. monogender pairs. I think even just the 10 pass would be much more workable. Even with just the 10x Pass, trading 250 passes goes from 50 trades, down to 5. (Unless I am just unreasonably bad at math??) I doubt you'd really need anything higher, I feel like anything under 5 trades is reasonable, seeing as that's the standard amount of trade slots. If you're at a point where you are sending out/need to borrow over 250+ passes, you're likely to already have more than a couple Trade Center Expansions ^^
