I recently found out that some weapons hide the enchants and only show the glow that comes with the weapon. Transmogging to these weapons will hide the enchants as well. This means that you don't have to watch your weapon drip mud due to the [Landslide]-enchant anymore!
I stumbled upon a thread on the WoW-forums, where a rogue called Töki has created an excellent list of weapons that hide enchants. Töki has categorized them by colour, which is perfect for those looking for a good transmog replacement. The list can be found in the European forums, right here.
