A vital part of the BB combat round is the ability to re-roll specific dice in a recently failed roll. However, there is no way to select individual dice from the previous roll, nor any way to specify which ones to re-roll. It's possible to visually inspect the die roll, figure out what size dice needs to be re-rolled, announce that to the other players, and then type "/roll d x ", of course, but that's kludgy and will get tiresome after the first few dozen times. This is a core mechanic for the game and shouldn't need to be kludged.
