My understanding is that only the host can pause the battle. I'm not sure if this was the case in early versions of the game, as we had some problems getting the game started when both players were attempting to unpause it. Having only the host pausing and unpausing will be much better.
By vote...(>= 50%)
I hope this is (>50%) and not (>=50%) or two player games will get strange.
Someone test this please and let us know what happens.
