I support that. Jira is a feature monster. It is aimed at producing nice pie charts, percentage numbers and lists (of solved, unsolved, analyzed etc. problems). A nice toy for managers. These are probably the people who make the buy decision, so it was clever to aim jiras features at this group instead of bothering with developers needs.
Gamification of jira may simply add more entertainment options. Not a bad thing, because the less these type of managers interfere with developers work through jira, the more useful code can be written.
I could easily image to give a character to every logged-in developer and let them run through charts or hop around in bug lists. The managers may virtually shoot at them with rocket launchers or laser blasters. Not bad. Go on.
The time is not far when I don't take a job anymore because the project uses jira.
