Cool thing about facts is you don’t have to believe them for them to be true 
(meaningful raids have 20 people not 25)
Also guessing you don’t clear heroic in week 1 and spend many hours a day gearing in m+ to give yourself a better shot at mythic bosses.
Or prepare 2 characters with full paragon chests ready and professions.
It’s of course fine to not do these things but we operate in separate words within azeroth so you not knowing how much loot I get is understandable.
