Despite hating how hunts and elite marks work as they are, I have to say I believe it's "Working as intended" however the mass of people doing it makes it seem broken. How do you fix this? any way to fix it now like giving the marks more HP, down the line when they aren't farmed as often the B rank marks will not even be looked at because it'll take too long and the reward is too small. The only error I with the elite marks atm was they gave EVERYONE Nauld. A bad joke for a system that has marks in every zone but they gave everyone the same one. I've seen 5 different B rank marks only killed 3 cause 20+ people on them kill them in seconds.
So in my final words: Working as intended yet very poorly executed.
