[Lord Azagthoth]

I have defined Extra Attack a little different. Instead of an Extra simultaneously attack, it's an attack which very quickly follows the previous attack that round. Players still wanting to display a simultaneously attack get a -2 per Extra Attack on their to hit roll. (1st Attack = 0 modifiers, 2nd Attack at -2, 3rd Attack at -4, etc.).

Players using the successive attacks get their First Attack at Full Basic Speed. If they have 1 Extra Attack, their second Attack is at 1/2 Basic Speed (round down). If they have 2 Extra Attacks, their 2nd Attack is at 2/3 Basic Speed and the 3rd at 1/3 Basic Speed. For the players, this is a one time notation on their character sheet when they buy Extra Attack.
