Subject says it all, we need more people to sign up and help defend.
There are 4 sieges taking place tonight between 20:28 and 23:28 EST that are currently showing less defenders than attackers. I'm pretty sure it's not intended by the developers to have these fiefs taken so easily. Personally I think they should do more to incentivize defender participation, perhaps a guaranteed 2-5 Strategus gold and maybe 5-10 for a successful defense.
Also, I don't understand those in an ambitious faction who don't take more interest in fiefs easily going to competing factions, especially those in close proximity to one another. Even if it's your ally taking a fief, come and make an interesting fight. That's what most of us are here for in the first place, right? Battles that matter. With more organization and teamwork than you might find on a native server or even other cRPG servers.
Come on down, join us and MAKE THEM BLEED for the land they want to control!
