Lack of TRUE pause decimates playabilty unfortunately ...
By "TRUE pause", I mean one where you can pause and issue orders. The end result is a frustrating experience, unless you're into overly simplistic button mashing senseless free-for-all's ... as that is what it boils down to when the heat gets turned up in this otherwise fantastic game. They should call it an RT or Arcade Game, as that is what it amounts to.
Nearly all elements of strategy are removed when you are not permitted the time to plan out your assault/defense. Adding this simple feature would open up this game to MANY more gamers.
Sadly, there are no plans to make this simple patch a reality.
