Epic Games Launcher - Worst software i've used since 2012

It does not download data all the time (it only download data for small increments of time and at very low speed) , but takes all internet speed for itself (when i turn it off other sites and programs download with full speed)

And… after closing and re-opening it downloads from the start - so its not even a download manager.

Whats the point of seperate program when it do not store download progress - its so stupid…why just not use Firefox or Chrome for download?
