Well you gotta have your momentum, it's vital for any guild.
Imagine if everyone sat at the precast waiting for people, it would be cockslap-happy hour.
I do the same thing, turn the camera, constantly buffing myself, constantly checking everything, pulling up my equips to see that I'm wearing the right gear even though I just checked five seconds ago and other things, like verifying we have everyone in the breaker team and the defense team on their places, running around a place we know is safe just to check again.
I also have the habit of each time I start a new server, I turn my bgm on and soundeffects, and just sit for a minute or two before logging in just listening to the login bgm, thinking about the feeling I had when I started a ro client for the first time and heard the *ding* sounds when logging in.
