Castle guards are not out yet. So the only base defense is primarchs. The PVP shield is down and there is no way to defend a base unless primarchs are there. This is absolutely ridiculous. PVP shields need to be up until castle guards are released so you can defend your bases. What a joke.
You can instantly walk into any base now and claim it if a primarch isn’t there. Even if a token primarch is there, you can kill it or attack the base and claim the castle.
PUT THE GOD DAMN SHIELDS UP! Honestly. This is a joke.
