I get that rng is rng, but after doing a lot of pet battles, I thought LFR losing streaks maybe could act like trying to capture a pet. When you try to trap a pet, if it fails, you gain a 25% chance on your next attempt. This continues until you successfully trap your pet.
So in LFR terms, maybe every time you don't get loot, you gain say a 2% better chance next time?
Another way I look at LFR loot is like casino tables. House is gonna win one way or another but if they never let you win a single hand, a single pull of the slot here or there you probably aren't coming back. House makes a lot more when they give people a little hope here and there.
