No, that's not true. Ship speed and world speed are two entirely different settings, my friend. World speed impacts build times and siege times, not troop/boat movement sppeds. That factor is controlled by the troop speed setting, which is stuck in first gear.
@darklazerman: Indeed, she did have everyone vote, so people have only themselves to blame. I voted for world speed two, to be honest, but the unthinking masses rushed toward the instant (relatively) gratification of 3x speed and the nostalgia of conquest without considering the consequences.
And, unfortunately, troop speed setting was never a factor upon which to be voted.
