There seems to be a break in the value of gold with some things costing thousands of gold and others costing next to nothing. A lot of mats are more worthwhile to vendor than to sell on the TP. It just feels to me like all methods of getting exotics should have an equal conversion rate (Drops, Crafting, Karma). It would make them worth a bit more if they could balance things a bit. I hated getting an exotic drop and then finding that it's only worth 1g in the TP. It would also increase the value of gold and encourage some people to buy gems to sell for gold.
