This is very true, and reworking the CSS/JS would be a pain in the ass, frankly, having to fiddle around and look for the possibly new css classes and IDs, and recoding JS to fit the new HTML structure. For me, it is not a welcomed change, and on another note, Wikia SHOULD support custom code more since they allow it. Why not support it if you even allow it?
