>> We use Confluence, Bitbucket... Asana (instead of Jira)
This is the thing with the Atlassian ecosystem. Whether you are pro-Atlassian or anti-Atlassian, there are only two sane options: you either all-in with everything Atlassian, or you are better off with nothing Atlassian. Mixing and matching products when Atlassian is involved is the wrong choice, every time.
The Atlassian suite as a whole is fantastic when the integrations are set up properly. If you dislike Atlassian's licensing or even one of their products, then you should not be using them at all. Don't take on 1-2 of their products, and then replace one of their other core products with an unintegrated competitor. Having a partial Atlassian setup is frustrating as hell to work with.
I dunno, JIRA works reasonably well as a standalone and integrates with everything under the sun. However I definitely see your point in replacing JIRA w/ Asana as it's really gutting the core of the suite.
