I made a post on another thread and it seems to take into account a few issues people have right now so it probably deserves it’s own thread
this topic will cover both the current muleing issue and the trading/jsp issue (TLDR at the bottom)
my proposition was to have an act 1 vendor which will have a certain amount of space to hold items that will be measured to have a sufficient volume to hold items for you on each mode(Hardcore, Softcore, Classic, Expansion) it wont be over the top but it will be enough for you not to have to make mules and it will only hold those items for each respective mode of course, which will free up some character slots for you to use freely where you choose to
second function of that vendor is to facilitate an in game hub for trading, currently there is a debate about sites like jsp and real money trading sites and the like, being able to post items for trade in game is simple safe and to the point, you will be able to keep your normal play style without having to open games for hours on end for every single trade you want to make
TL:DR - Act 1 vendor which will hold items for you instead of making mules which will also have an in game trading hub where you can post items safely
