Half and Full Actions make me feel dirty. The AP System really was much better than the old system.
Now that Beta1 's RoF rules are dead, I'm all for bringing back Action Points. Think of how much clearer the wording would be: "Characters have 3 Action Points" instead of "Characters have 2 Half Actions, which can be combined into 1 Full Action [with some exceptions], plus 1 Reaction." Yes please. Extra tactical flexibility would be the cherry on top.
