Well, it's been asked before, but it's been 8 months and it hasn't got any easier.
Epic is by far the hardest silver badge. Only 103 of them have been awarded so far. The majority of gold badges have a higher count; except Copy Editor (80), Reversal (49) and duh - Legendary (30).*
Should the requirements be lowered?
