I can't disagree with those points, which is why I said:
the question is whether the tradeoff is worthwhile.
The key is to remember that there is a tradeoff here, and try to minimize it. The game should not only be possible, but fun and manageable, without the pause feature. Huge battles in the Total War series just aren't manageable without pause, which is why only small skirmishes are realistically viable in multiplayer.
