About balaur sieges

Well, I never saw a balaur siege on retail, so I can't afirm anything, but a few minutes ago I saw them getting crimson temple in 15 minutes, without breaking the gates, i don't know if they're supposed to go straight to the deity, so I'm asking this here.
Also we can't aggro them out of stallari, I don't know if this is right too, there were more than 30 asmos and all we could do was kill a few legendary balaurs....
We used insignias of protection on the deity, and it didn't help at all, its almost impossible to defend it with lumiel's current population, as we can't lure them out of stallari's target. Can anyone answer the stuff i asked here/give some suggestions? =/

 

Balaur Sieges have to do with how much and how long a faction has control of forts. The longer the more likely they will go in and start taking forts. This is a balancing feature so that a faction doesn't retain absolute control of forts. The issue is not the mobs as far as I can tell. I will say though 30 people is not nearly enough for a defense. Aside from being a place to hide during pvp there's no actual need for the Ingg/Gelk forts due to the fact that Silentera portal isn't controlled by if a faction owns both its forts. If ya want to get a fort you'll definately need a bigger force.
