Jira almost has too many hierarchy options / flexibility.
Epics, Milestones, Initiatives.
No two firms, and often within a firm.. no two teams has a similar definition / system in how they are used.
My last manager it was like a sniff test / definition of art thing. Constant arguments about epics being too granular or not granular enough. Bumping tickets up or down the hierarchy was hell and lead to many many hours of wasted efforts.
