Ok, let's agree it's about figure of speech. So yeah, they are not mandatory but give quite a lot of advantage over people who don't have them. And imagine that people who do Mythics are quite competitive in nature. As someone before said, it's a mentality problem and that is true. This is hardcore raider mentality. Hardcore raiders didn't ask for this RNG shitfest. Hardcore raiders are all about efficienty; effort -> reward. Why couldn't they keep legendaries as not high end items? Something for less competitive crowd to be happy about? Raiders don't need legendaries to feel cool. Killing bosses makes raiders feel cool. And for hardcore raiders legendaries are nothing more than tools to kill bosses faster. Those things should not be rng. Tools to kill the boss should come from working for them.
