I think calling Atlassian mediocre is a bit generous. Confluence is a steaming pile of burn garbage that still can't get basic thing's like SVG working[1]. Atlassian can't give a darn, they have their captive market and they are just riding the gravy train now. The last good thing they did seems to be to buy trello, but they will likely turn it into garbage if the rest of their portfolio is any indication of what to expect.
