I'm concerned with people rolling their own dice I mean it's not hard to roll a d20, get a 1, and be :o well I got an 18. I think the rolls should be left in the hands of the DM and the action dependent on that roll belong to the player. (Plus I may have a dice back but maybe others don't.)

There are group dice rollers on the web if the GM wants to go that route.

Though, I don't think he mentioned anything about who rolls the dice. It can be assumed that he'd be the one doing it for the reason you gave.
