Well, I still have a long way before being a heavy hitter, but I got some SEG spawnings from time to time, and I would gladly share them if it helps anyone.
Of course, your idea will need a really good coordination between players to work. But it should give results.

This idea is interesting, could be like a more specific counter-measure for high HP guards. Just like the group raids, but more focused.
Oh, and Chibikika, I've read your post yesterday regarding your timezone and the current strike force availability. Sorry to not being able to answer sooner. I'll get into it now.

I just can't understand Nutaku. I can't believe that they're doing this "nope, this mess was intended" shit for the second time.
