Actually, you can get all of these in the glass desert. Water slimes are in the pools in the "fortress" area (large temple-ruin in far back) after awakening the area. Rock and dervish slimes are in the same area.
But, yeah, that is pretty typical of the random generator giving you bad trades.
The next three updates are supposed to make changes to the Exchange, but it is unclear how. Based on what we have *now*, a Reputation system making trades larger and with better deals would be a good fix. However, the game plan road map discusses "impressing" the NPC's to get special missions. There may be a reputation system coming, an we have to see.
