The players who have very good or very bad luck will be the ones who tend to post their stories (there's a thread elsewhere about a player who snagged two MTM Megatrons in one or two tiers of the bridge plus his weapon; incredibly good luck). The average schmucks don't tend to tell their dull stories ("Yeah I made 3 pulls and got 2 bots and 1 alt").

We'd need a truly unbiased random sample of players to get an accurate picture of the odds and we don't have it. Barring that, the simplest explanation is likely the truth. Granted this is Mobage and they are experts at designing these "suck you in and then drain your wallet" type games so.. who knows, really.
