Command and Reknown ranking system worked before and there's no problem with this for not work again. Not to mention, Command and Reknown ranking systems weren't hard at all. Just play any type of contents you like and you get rewarded for it. It gave loots, gears, currencies and boosted new people with good equipment without having the requirements to do Ops or master FPs for better gears.
And I won't talk about cosmetics because people would make their own from anywhere.
And reason why I asking to remove the level sync is because it's time consuming to deal with every enemy around. You said video game is a big waste of time but you don't realize it's for many people a way escape from real life, relax and have fun but not waste time fighting against literally every enemy in the area. Not to mention it's annoying when you're just trying to get datacrons, crafting components, lore objects and just generally explore the planets you've been before more.
