Duplication for Mirror Images in HERO System Discussion Posted Tuesday at 11:16 AM · Report reply 2 hours ago, Doc Democracy said: as a GM I dislike one player being able to take more than seven or eight actions in a round, especially if everyone else only has three or four actions. I even persuaded one of my players to take his SPD 12 speedster down to SPD 9 and only that far because I knew he was likely going to need 2 or 3 phases of recovering during a fight every turn. Duplication also ramps up the number of actions per turn which can seriously slowdown a game and make other players get much less spotlight during the game. This. Speed is the broken part of the system.
