> Who the hell wants to create new blocks for each sub-heading and paragraph when they're writing regular articles? The old editor is much easier to use.

You add new paragraphs by just pressing enter, and you make it a heading by typing (part of) "/heading". It's less work than in the old editor, and it even produces reasonable markup (entirely unlike the old editor). If you don't want to design a new web page, just... don't? You don't need to press every button available.
