I spent many hours today cutting, gluing, and assembling pieces for my board game prototype (again).
Is there such thing as an allotted RNG luck for drops? Wouldn't that defeat the purpose of RNG itself?
Well, "true random" means you could possibly go forever without seeing a single drop you could use. That's not very fun. It certainly brings high highs, but also very, very low lows. There are safeguards for many types of loot, from bonus loot coins to Garrosh heirlooms, to make sure that you do get something given enough time. Diablo 3 has a similar system in place now if it detects that you've gone quite a while without seeing a legendary drop. I'd rather my chances get a nudge in the right direction than rely on "true randomness".
