Strategy? The chance of finding an item is always unexpected how many or how good the item you might just get is always a question that can only be answered after the job is done. Lets say you have reserved 5 items slots in your inventory and you queued 3 jobs of work, each for 2 hours using premium, but when you checked it, you found 6 or more items but you didn't expect to find more than 5. So it turns out that some of your items will be rejected. And how can the game automatically dispose items in your inventory just to fit the new items in? How about if your golden buffalo gets dropped?why is it a flaw if someone cant get an item because they were too stupid to make sure they had room in their backpack for items picked up from jobs before doing a job? its called strategy, and its what this idea would invoke more of if implemented. i like it.
Plus this idea has another fatal flaw. Normally when your bank does not have enough space, you would just keep the useless items you have in your inventory and just sell them only when you are going to buy something so that you won't take risks losing your extra money on a duel. Storing the items you plan to sell in your warehouse will just cost space and could lead useful items to be rejected forever. Products can be stacked but items can't. And items are more expensive than products when sold.
This idea is a disaster. I hate it.
