*disclaimer: this is not meant as a complaint, just observation*
each of my 1k orders (coming from different orders) were missing different rares (1k short one rare, other 1k short two), but they didnt overlap, so it worked out that i at least got some of everything. though, i ended up oddly short on almost all of the rare armor.
for random URs, i am suprised every year how 1 per 100 always seems to equate to 1 per 120. in all my ordering (ive ordered at least 1k each year starting with the chip tokens), i think i have equalled 1 per 120...missing completely once, but making up for it with a second UR once. even though i feel mathematically deprived by an UR (the extra 20 packs add up to over 100 at this point), i am still very happy with my random pulls this year...they were tokens i was wanting to get (the quiver of annointment 'mysteriously' disappeared from my want list a few days ago).
i know it has been said that URs arent technically a random 1% chance...there is literally 1 UR in each block of 100 packs. which makes it very important where in the run your order starts from. im suprised noone has suggested it before, but how about:
-small orders get pulled from broken blocks (obviously the only option, they may luck into an UR or not)
-1k orders get an exact 100 pack block (that will contain exactly 1 UR), then 20 more packs from a broken block.
-8k orders get 9x 100 pack blocks (exactly 9 UR), plus the 60 more packs from a broken block.
this set-up prevents things like a 1k order getting the last 60 packs of one block and the first 60 of the next and not getting the UR out of either (it also prevents the possibility of the 10-100-10 and getting 3 UR, for better or worse). so, orders will be guaranteed 1 bonus/random UR per 100 packs received, with the possibility of more in the extra packs. the only thing about this is that jeff would need to have each 100pack block seperated to start with, and only break them open as needed for smaller orders and additional packs...i have no idea how the tokens currently arrive to him, this may be easy or impossible.
