The difference, as I understand it, is that if you're only getting + / - 7 LP gains or whatever, it takes a lot more wins to get back. So it's more of a grueling process before divisions start skipping.In the old days of the pure elo system people could tank their elo by dodging, so bronze to challenger runs happened a lot. There's no difference essentially, the bronze/silver games are stomped even harder than gold+ games.
Fuzzery didn't believe the madness of bronze so he tried duoing with me...and got a support Nasus. We still won though.
