I can't say I've always listened to those who've said it's best to wait..
But what you've said does make sense, especially when there are innocent people at risk. Anyone who isn't prepared for repercussions doesn't tend to announce themselves?
I'm a causal member of the defense team, but I'll be ready. I'm a skilled climber, and like to think I've got some ability to be stealthy. Also, I have a lightsaber. Anything I can do to help scout for more information?
