Jira is agile: do you use Jira and Confluence and consider this one of the main reasons contributing to your agility? Congratulations, you are part of the problem.
Boring Backlog: fixed really hard bug? Implemented complex algorithm or cut processing time from 10 hours to 22 seconds? It doesn’t matter, just pick another thing from backlog. Scrum/backlog promotes code monkeys where good effort isn’t rewarded. Personal efforts don’t matter.
Story points implementation: as long as story is implemented, quality or tech-debt doesn’t matter.
I have my complaints about Agile, but a bit different from this list. Teams I've worked in have generally tried to spec in quality control measures into story points, to prevent some of the issues mentioned, for example.
My issue is almost always just that the top half of the organisation does not, and will never, conceptualise a software project like agile demands. Business will always want X scope within Y time. And Agile demands that at least one of those to be variable. The backlog represents scope organised by time. Want X features complete? Check the backlog to see when they'll be done. Want to deliver after Y time? Check the backlog to see what features will likely be ready by that time.
But business will not accept that. They have scope requirements and deadlines to deliver within.
