Welcome to the forums Legolas (best character IMO)
Ah.. the old "The game is too slow and faster would be fun" The plausibility of your suggestion all depends on how much faster you want it to be. Currently, the average distance between bases is id say 12 hours, give or take. A helmsman can make that in 6 hours. So if you let a martyr/helmsman appear next to your queen's base and don't you schedule a sub to defend overnight, bye bye queen. Overnight attacks are the worst thing to happen in this game, and they can and do occur when a sub travels at X2 speed.
Now, imagine every single sub traveling at an additional x2 speed. That 12 hour time i talked about earlier is cut in half, and then half again. A martyr being able to reach your queen in three hours is a scary thought. The normal X1 speed is, in my opinion, the fastest this game can fluidly run at without pauses, in my opinion.
You may ask? "What if the game is fast enough to finish within a day, so the whole 'sleep' thing doesn't ruin you?"
A game where subs land in minutes, not hours. That's an interesting thought. Playing Subterfuge for 3/4 hours straight, with no breaks would be very intense, not to mention stressful. To cram a 10 day game into 4 hours, it would need to be at x80 speed. The 12 hour travel time, cut down into one and a half minutes. Not even enough time to react, much plan an antiquate defense. Also, having any form of speed specialist would create subs that, in all practical matters, would teleport to their destination.
The concept of a sped up subterfuge looks fun on paper, but in reality is crushed by math (Like many things in this world).
Godspeed on your future travels, legolas0011.
