hehe,
yes, I totally agree that 70% is the same number from whichever end you look at it. the actual picture is, that a considerable part of people will accept such return with opalo as the total loss is not that big. but what the system "forces" people to do in their wish of advancement over a time (major interest in any entertaining activity) is depositing more and more. there are those that can take the 30% or whatever loss with MM but 99% of players can not. I think this is one of the biggest flaws in the system - people do not get encouraged to advance, the bill for that is rather big. this is why people are leaving - the fun is not worth it...
long story short, 70% on opalo can be ok but be a killer on MM.
