(From another thread on General.)
Maybe the vendors should offer scaled cubi box packs (prices are just suggestions / a guide).
5k for the Tin Cubimal Collector's Box / a common with a very small chance of an uncommon (no semi-rares, rares or uber-rares). Your standard piggies, chicks, butterflies, etc. Could also drop very, very infrequently from (say) tree-harvesting activities, to get the sickness of cubimal addiction kick-started.
10k for the Copper Cubimal Collector's Box / an uncommon with a very small chance of a semi-rare or common (no rares or uber-rares).
25k for the Molybdenum Cubimal Collector's Box / a semi-rare, with a very small chance of a rare or uncommon (no commons or uber-rares).
50k for the Whopping Diamond Cubimal Collector's Box / a rare, with a very small chance of an uber-rare (the top three rarest or special cubis) or a semi-rare (no commons or uncommons). No option should exist to just purchase an uber-rare box (with Rooks, Rocks, Gwens, etc.)...you have to try your luck with spins, Rube, other players who like to trade and sell, or buy a Diamond / rare box and cross your fingers.
Could cut down slightly on the piggimal (etc.) spam all over Ur (hiding them is fun, don't get me wrong, but there are possibly more piggimals (etc.) than people actively cubi-collecting at this point), and scale a little so newer players can start a collection and then afford progressively "better" cubis as they start generating mad amounts of currants in-game.
Collectors would have to save more currants before purchasing boxes, but would have less chance of winding up with 493 piggies to distribute throughout Ur to hordes of people who already also have 127 of them. (Slight exaggeration.)
