"Barely sufficient to stop people from switching to Slack" seems to be Atlassian's target.
Atlassian abandoned HipChat's bug tracker, and put up a fresh JIRA that they discourage you from using at several steps. That's one way to get the bug count down without fixing any bugs.
I've logged a number of tickets against their product, their solution seems most frequently to be "we're merging this with another ticket that's about 50% related, fixing some other issue, then closing this ticket and opening another one for other issues since merged into this ticket, elsewhere." If you follow the ticket trail around long enough, you may see your issue fixed, but I haven't been that dedicated yet. Their support process is certainly pretty crappy.
