I suppose one could even pare this all the way down to rolling just 1 or 2 die for each dice type in the roll, though that probably won't float most boats....You honestly think a typical gamer's polyhedrals -- or even the atypical GameScience polyhedrals -- are more random than a seeded random generator? Really?Considering that there is no such thing as a truly random number in electronics or computing, I would say no.
Are you sure? Have you run a chi-square test on yourself?Plus tabletopping is one of my ways to get away from technology so I'm biased.
Did you only play melee characters in 2E? I ask this because even at 5th level, Wizards were starting in on their path towards buckets full of dice with Fireball & Lightning Bolt. 4E is by no means out of line with previous editions in using numerous amounts of dice for dealing damage.
