I agree with you about the dice roller; pseudo-random is plenty random enough, this is overkill. I hope it doesn't cost them much money to access this 'quantum' device! And yes, as you say, most people don't truly understand probability and randomness and will continue to complain, never understanding that looking non-random is a sign of true randomness... NEVER rolling eight "1"s in a row would mean it's not random at all!
However, the character sheets thing has the potential to be a game changer, much like the Token Actions ability was. I just wish I knew more about what, exactly, it is they're planning to do! I have several projects, one major, a few minor, and a couple just-games, all on hold or at various levels of stasis, due to the fact that I'll most likely have to either redo from scratch or make massively major changes to them when this comes out. For example, I have a setup with literally 100 different critters in it, all programmed with macros and everything, with the Pathfinder rule set... and I'm not doing a damn thing with it, because as soon as this upgrade happens I know, I just know, that it's all going to be obsolete and I'm gonna have to start over! I've also got something even more ambitious on hold, for the same reason, and the various games I'm either hosting or playing in... yep, down to minimal changes, if any at all, to character sheets because really, why bother fixing something that's about to break anyway?
And yes, there are other 'minor' fixes they could make, but hey... all in good time, right?
Keep up the good work Roll20, I'll wait!
