If it's true they have hit a coding limit on bank space and backpack space, them remove the "exclusive" tag from bags, or at least allow some nice BTA/BTC bags to drop in quests or as end rewards. Make bags for potions or scrolls. Soething like that. Also, what was that game where you could actually buy a real mule to hold stuff? It followed you around, it could fight but not very well, and could be killed.
Not against player housing, just wanted to recommend some options for storage.
