Amusingly, it used to be great! When I first started using JIRA, it was just markdown. Then they introduced their WYSIWYG editor, but at least they still had the button to see the raw markdown and you could still edit the raw markdown (but the GUI made terrible markdown so if you wanted to use markdown you better start with that and never touch the GUI). And then I guess at some point they just removed the markdown part?
