I agree with everything DEmersonJMFM just said, and with Kirkburn's more recent replies saying similar things, it's becoming clear to me that the people commenting here complaining about their layouts being messed up on large screens are the problem , and are the reason why Wikia made this change.

I've always ensured that my navboxes/infoboxes/tables/advanced-whatever-else looked fine at the smallest article-width Wikia supported, so the only thing I had to update was my custom CSS.

If everyone else had bothered to check their layouts at the smallest supported article-width, this change would not have been necessary. So, thanks a lot, wide-screen whingers.
