Not everyone seem happy with Patch 1.13, and the new, larger stash that was promised yesterday. Since anyone can make unlimited accounts with unlimited characters, there is already infinite storage space if muling.
Bashiok commented on this just a few minutes ago, saying:
We asked for community feedback and a larger stash size was in the top three most requested changes.
Just out of curiosity, what were the other two?
Bashiok: Higher resolution, which we unfortunately just can’t do because it would fundamentally change the game and require a huge development investment to have the game/servers spawn enemies farther out, have them aggro from farther out, and even then it increases travel time to the player… it’s just a mess. Apparently increasing the resolution in LoD was this gigantic issue so I think the idea of increasing it again makes some of the old time programmers want to curl up in a fetal position.
And new end game content, which we do want to continue adding, but just wasn’t possible for this patch.
