re: Rolled HP
Um, I think math comes to the rescue before we fight
Using Statistics, you can show that the effect of rolled HP will not differentiate much from the effect of simply average the die as you increase the number of times the die is rolled.
Basically, as the number of rolls goes up, the std deviation will shrink (you get closer to the average) and what many people remember as wildly differing HP totals for characters of the same class was the effect of CON being added.
This was ironically more noticeable in the lower die classes like the d4 and the d6.
Ex: A wizard from levels 2-11 will gain an average of 25 hp, however, the difference in CON gain of say a 12 CON and 16 CON is 20 HP. The std deviation is SIGNIFICANLY smaller. The CON basically overwrites any effect from the rolling of a die.
