Dev here. I worked in the company that used Jira. Used it for 4 years. It was really useful. It is anyday better than getting tasks over email. We had very minimal customisations. A simple set of swimlanes that we update throughout the product development process. From what you are telling it looks like your team had other problems in delivery. You tried to solve it via Jira by adding new custom fields and forcing people to update them. Solving the deeper issue would have helped there. I have been able to track my deliverables. See how my team is performing. Plan for the next sprint. Perform retrospectives and capture action items. The tool hasn't broken while doing this. UI is decent. I really don't see a problem with the tool, it serves its goal.
