Rogue tower and peacetime?
(EDIT: I think I found it: viewtopic.php?f=24&t=1608&p=27070&hilit ... wer#p27070)
Anyway: what about adding a tower that, instead of throwing lethal short-range boulders, throws pebbles (those stones the Rogue throws)?
It would have a nice range, but would be weaker than Bowmen's arrows, it would be cheap and fast to build but frail and have less attack speed than Bowmen and Crossbowmen.
Definitely, it would be worthless lategame: one bowman would be cheaper, more powerful and not much easier to slain. Yet, it would be able to take out little militia forces without problems, thus being a defensive tool against rushes, thus making it possible to remove the peacetime.
Of course, you would build it right next to your first buildings... its slow attack speed means that a few Militia can run past a line of these without many problems: a defensive line made with these wouldn't be useful unless paired with your own Militia, and would still require time and stone for the road.
To sum it up, its usefulness would be limited to the early game as a counter for rushes: it would be too weak and frail to stand a chance against actual attacking armies and would be an hinderance during sieges (4 Bowmen occuping its space would contribute way more), but would be a good defence agains rushes.
What do you think about this?
