One thing for all the turtles to keep in mind - while DoF doesn`t penalize turtling, it doesn`t reward it. You want to be out there - visiting local villages and mercenary camps, fighting various PvE battles, fighting other players, questing and trading - it`s the best way to quickly acquire resources.
Also keep in mind Rollingplain can put our mass sword and shield infantry, that are really efficient against ranged units during castle siege/defense.
Of-course no question about it - Rollingplain players will be better of laying siege in team with another player, who`ll cover the siege equipment. But having large cavalry force, allows pretty good raiding in PvE, on top of that Rollingplain offers plenty of gold - so it`s possible to buy some wood and siege equipment.
