Hardcore... How would you define it?

[Goodberry]

In my personal book, "hardcore" players are those afflicted with an enormous delusion, i.e. that being badass in a game makes them special snowflakes overall, with a right to look down with stern pity to mere mortals who do 1.5 DPS less or aren't able to one-shoot EX Titan.

In fewer words, billionaries without the billions. :P
