How do you want to know, if the majority is against the old system? There is noway in knowing that, because the majority is not in the forum in will never be there. Even the poll about the armor system is hardly representative, also I don't know how easily you could vote more than once in that poll if you really wanted to.
Also you don't know, how many of the pollers ever played the first game, so if they were really able to evaluate the difference.
Pen & Paper games are quite popular and they are pretty much all about rolling dices. Calling the D:OS1 system RNG is just abusing prejudices and misunderstandings.
