But I think a big part of that might have been the build your character picked.

Fort just isn't designed to deal with neutrals in any way shape or form. When you combine that with the massive Fort/Nexus numbers and the deletion of two really big, competent leaders in the fort opposition cabals...

It ends up being the Fort's biggest foes now are the Nexus, which they are really ill-equipped to fight, since they have to deal with both inherent RP -and- PK restrictions. A lot of Fort powers just aren't that useful against Nexus, and a lot of Nexus powers are expressly designed to work very well against Fortress when Fort is in power.

It also doesn't help that whenever Nexus is outnumbered by fort, they just wait around, without needing to really do much. Few if any Forties will actively hunt them.

When Nexus outnumbers Fort (or gains some other advantage), they just stroll right in and roll over everyone in their way, and Forties die by the dozen.
