There is bad luck protection. If you play enough, you WILL get your legendary. Simple as that.
It's the same argument about Welfare Epics in WotLK. What does it matter to you? How does someone having a Legendary affect you?
Someone having a Legendary doesn't affect anyone else.
If you think this game is competitive then maybe you need to reevaluate your life. Nothing about this game is competitive unless you make it that way. Blizzard has tried telling us this for damn near a decade now, and still people fall into this trap.
Quit making the game competitive, quit comparing dicks, and maybe you will actually enjoy the game and the systems in place.
