They still do these q&as? Thought everyone at blizzard was dead.
And The warp back would make no sense. At least in the refund sense. If it costs money to initiate a warp in, wouldn't initiating another warp(albeit to somewhere else) cost you the same amount? I'm talking lore wise. Any sort of warp, no matter where it is going, should cost minerals.
Plus terrans laid claim to the ability to get refunds and it has totally never been done before (*cough* undead *cough*)
