Another pretty bad trend I see is designers who don't make pragmatic tradeoffs for the underlying technology. Not incorporating reusable components, not considering rendering times, not considering the design language already established. Sometimes designers decide they know better and that usually rubs me the wrong way.

Worse still are designers who don't use established patterns, not just within the company, but like throughout the web. They want to make something truly unique that would completely ostracize the user, not to mention make it waaaay more time-consuming to develop. Get a grip, this isn't your art thesis, its a business.
