Yes, Blizzard please, anything for increased inventory space. More characters, or more stash tabs per character, please just give us something – it’s incredibly frustrating being capped to 20 characters.
You could go the exta mile and implement the Unique Collection stash from PoE, which allows you to store 1 of each unique / set item. I’d even pay a small extra fee for that. But if that’s too much to ask for right now, please at least give us more characters or stash tabs.
