Not every drop is suppose to be profit. If you don't like what tier 6 keys give then don't make them. They shouldn't just be a guaranteed godlike drop, and I'm sure you'd rather get 6k back than a heroic.
They're meant to be a risk. You have a 1 in 20 chance to receive a godlike from them as well, which will make your money back(assuming it isn't a railgun) if you do hit that.
