What if you have a job unlocked, queue pops for that job (i'm assuming it tells you what you'll be playing before going in so you can switch to that job before entering) and then....it turns out you don't have the weapon for that job specifically in your inventory to switch to....or you do, but you don't have the proper equipment for that job and instead you're just using the weapon and running around naked?

Something to consider is you'd have to ensure having the equipment for each job you can possible get, currently in your on-hand inventory. Which means getting a system like this to work, may be a bit more complicated.
