Use GUI HTML editors for editing wiki content

We're looking to improve the experience of editing pages in our Wiki, and I'm wondering if we should just ditch "wiki" syntax and just support HTML and use a nice in-browser HTML editor.

It should be easy for us to continue to support CamelCase and square brackets to link to other wiki pages, so what else would be missing (other than an annoying wiki syntax)? Does anyone have any experience on going this route?
