There is little point in using Transmogrification if you cannot hide or alter the enchantment glow because they are simply too obtrusive. Enchantments like Landslide and Power Torrent especialy completely obscure the entire weapon, making any attempts at customization of the weapons meaningless. All you see regardless of what weapon you have is a huge, over-the-top glow.
Aside from obscuring the weapon model, many weapons just do not look right at all with certain enchantments on them. It seems wrong to offer such a large amount of item customization then deny us from being able to change the one thing that stands out more than anything else.
I have to suggest either adding the ability to hide enchant glows or allow the Transmogrification source weapon to overwrite enchants on the target main weapon.
As it is at the moment the Transmogrification of weapons is not the customization it's purported to be.
