Yeah I was asking a week or two ago whether people minded that. There's an argument for both (base and no base) but at the prices these things are you'd think providing a base to give people the option would have been nice.
To me visually the desert sand is part of the look for the Dew (in the same way snow is for a Taun,) so it's nice to have it on a base.
While the Dew standing directly on the display surface does solve things like height of figures displayed interacting with it, I'd say most, if not all people would prefer a base or the option to add one.
There aren't many 1/6 items that have no display stand/base, at least at the high-end. This seems to be one of them.
