Most fights tend to punish the first mistake with death, or a loss. Name of the game. The only interrupts I don't like are ones that have no logic behind them, or try and fill in the smallest time gap. People are really bad for that sometimes, especially if they know their opponent won't say anything. I'm sure some here have experienced it., ain't gonna drop no names of who does it. Those can get really bad, but interrupts in general are fine. If you're throwing five punches, I don't see any reason I have to write it so I'm dealing with five, if I can stop you at two or three.
