Relatives of victims from across Northern Ireland's political spectrum were interviewed by the University of Ulster in one of the largest studies of attitudes towards the PSNI unit.
Professor Bill Rolston, who conducted the research, said an alternative should be established.
He said: "The onus is on the state to provide an alternative to the HET which avoids its mistakes and gives relatives of victims what the HET seemed to promise - investigation, disclosure, support, information and perhaps even some sense of closure and justice."
The HET, which examines unsolved Troubles-related deaths, was criticised by an inspectorate last year in a report which found it investigated army killings less rigorously.
Its future is currently being considered by Chief Constable Matt Baggott.
