I also like butterflies and wouldn't want them to disappear, but I understand they can ruin certain looks. Butterflies don't go with everything.
I also don't dislike the elemental form of sorcerers, but it irritates me that they don't have the Veil of the Elements toggle, since druids did get it, and I don't always want to be hidden under the elemental veil. Wouldn't it be easy to add it to the sorcerer too? xD
Some visual effects should be individually toggled. Removing the overlay effects from the options is too much; it takes everything away, and there are things you want to keep.
Or have a better cosmetic system, so we can add several effects (have a hat and the butterflies, for example), as well as more cosmetic slots, for example, for lutes or quivers without competing with cloaks, and cosmetic slots for gloves and boots, etc. There's a lot of room for improvement in terms of cosmetics. If we had a better cosmetic system, we wouldn't need things like curses to add visual effects; we would add them to our toons to our liking.
