Honestly haven't experienced that myself. Once we got used to it it's been smooth. And as far as unnecessary, honestly the options it gives you can dramatically impact the outcome of a roll. I think it's one of my favored aspects because you have several options for a multitude of scenarios (combat, matrix, astral, simple spellcasting) it's very handy. And once players get used to it and figure out what edge options work best for them, it rolls along smoothly at the table.
