If I want to get and defeat everything, I go play single player games. In multiplayer I see how far above 50% I can get, knowing that I will never reach 100%. And it's alright by me.
It's a multiplayer game guys. Events are just tools to outplay other players. Doesn't matter how hard they are, they are hard for everyone. If all events could be completed by everyone we would have identical stats
The top guys need tools to outplay each other too. Lvl 100 boss or master raid boss is few of them. It's not a tool for you, it's a tool for them.
Too bad it's pay to win though, but that's just game design.
