Right.
So how about fixing things so dices go evenly too? Haven't you been in games where you got all the good dice; and in other games where the opponent got all the good dice? Weren't any of those tournament games?
Oh. Wait. There are probably still some among us that believe that skill alone can compensate for rolling all 1s and 2s vs. the opponent's 5s and 6s
If it's random leave it random. Otherwise it smells too much like choosing the winners in advance (or a programming situation that could lead to that).
Besides. First turn doesn't guarantee a winner, and isn't necessarily an a huge advantage on some of the maps and settings.
