For buying, it would be good to just be able to enter in a number, or use a +/- 10 button or something.
For opening, 10-20 at a time would be nice.
More would be good too, but understand if this could cause some compute/calculation stress.
The “animation” of opening the boxes just takes too long. It’s a very inefficient use of time, especially when you just end up seeing duplicates of low rarity skins.
A good example of ‘bulk opening’ would be MTG Arena. Where if you bulk open packs, it only shows the results of the higher rarity items.
