you do realise that the last loot system was also just pure luck right?
the previous system with personal loot did the exact same thing as this does, an item dropped and everyone who had the ability to roll on it needed it and it got given to someone, it just all happened behind the scenes and you didnt see it,
now an item drops and you can pass on it if you dont need or need if you want it, its just a better system,
also kinda difficult to complain about a system not working for a “solo player” when you are literally playing an MMORPG, just incase you forgot the MM of that stands for massively multiplayer
