Are you seriously forgetting who made this game? Are you not aware of how pitifully little information they give us about what affects game world behaviour? Someone who gets alot of 100s might be getting them because they roll with 6 THFs all with TH+ maxed out on a new moon, on lightsday, each member in the zone carrying exactly 3 rarab tails, all players having names starting with odd letters in the alphabet and lengths of no more than 8, but no less than 5 characters.
Lastly, if I could impart just ONE ounce of statistical common sense to the general population it would be what I am about to yell at you over the internet:
YOU CANNOT MAKE JUDGMENTS ABOUT THE "RANDOMNESS" OF A SYSTEM WITHOUT A VERY LARGE SAMPLE SIZE. EVERYTHING IS
POSSIBLE, BUT NOT EVERYTHING IS
LIKELY.
There is nothing stopping you from rolling 999 every single roll you ever make, except for the fact that it is incredibly unlikely. However, from a statistical standpoint, saying "oh, I rolled 500 three times in a row so the system is biased." is just HELP I AM TRAPPED IN 2006 PLEASE SEND A TIME MACHINE.
From a statistical standpoint.
