For example: on the pages, under "XXX pages on this wiki" and search bar, there is a line, which can be replaced by image. Since wikia was with fixed width it was fine, but once the fluid came to be, the image wasn't covering from left to right on all the resolutions. The fix was to stretch it, which results in blurring and bad aspect ratio. Another: local navigation header image: on fluid the image starts repeating and end up not as intended, so when adding such image, you have to keep that in mind, but still won't end up as the way you want. Tables on pages: wider screens end up having big empty spaces on the left and right of the tables (that's if the table was intended to take the whole width and no text on it's sides). Pages layouts: on wider screens, all pages contain far more useless empty space and if you have for example 5 short sections with image for each section, due to wider screen, more words will fit into a single line, meaning wider screens see less lines for the same amount of text, which results in next section to start earlier (since the section will have less height on wider screen) and if you had images for each section, they will go into the next section. So if you had 5 images for the first 5 sections, the 5th image can end up going into the 6th or 7th section. You have to add breaks to prevent that, which results in more empty space... It can destroy a background too, since some backgrounds are not made of 1 color and if it's being split, even if you choose middle color, it can still look very weird, let alone if it was some image/shape. Those are the first that come to mind, but there are more.

Either way, that's in the past. No one listened then, no one will listen now.
