Surely there is no need to refresh the client page each time any security is checked on the server-side, and if security is that tight then only when a client requests a download or a request to alter the clients details, files, data or information on the server-side should a need for any security checks to be made and any information on the current page that has changed should be refreshed NOT the whole ■■■■ application so we end up at the start of the launcher index page every 30 seconds that the launcher refreshes right now? 
Quite frankly the standalone launcher on the PC has obviously been poorly designed and programmed from the start, it has never performed well at all compared to the features that are available via an internet browser, ie: Epic store and market place
If it was down to my decision I would totally scrap the current PC standalone launcher and totally have it redesigned, programmed & implemented, properly.
By all evidence it makes me wonder if anyone at Epic has ever checked to see how well the standalone PC launcher is working, or if indeed they have anyone assigned to maintaining the Standalone PC launcher at all?? Quite frankly, an Intern could do a better job!
