While out exploring or farming, once your inventory gets full, you have to stop and head back to town to sell / store / breakdown equipment AND then get back to doing what you planned on doing in the first place.
Suggestion
What if we had a companion that we could call ( like in ESO) to either sell or store items so we dont have to break the flow?
You call a courier / raven / wolf that comes to you inthe world, you place your items in its store and mark it for storage or selling and off it goes.
