Terenas early instance group forming

[Concillian]

Wow! It was 1:00 AM when we finished Shadowfang, and you went on to  Blackfathom! You deserve an award.

I don't think it was after 1am here (pacific), but I finished Blackfathom around 3 something.

1. Being silenced. 
Is this avoided for a mage much the same way aggro is avoided? Does it relate in part to physical proximity?

Yes, this was proximity to those ghost paladin guys. They have a silence 'battle shout' This is why if anything got pulled off the warrior, the priest and I would seperate ourselves so only one of us was silenced. If you stay out of range you won't be silenced

2. Killing Arugal.
I found that no matter where he teleported, I could nuke him without chasing after him. So I did, and came close to killing him. The priest went dashing off (following you and the warrior I presume) and never cast a single healing spell on me (though I thought he would). So, was this my error or the priest's or simply a lack of communication?  I did note that you also came very close to death after I got killed, but from where my corpse lay I couldn't see exactly what happened. Next time I go I willl inform the priest prior to the fight what I intend to do. Mind you I am not complaining (I am very aware that I made a couple of errors earlier in the instance)--I just want feedback.

I moved around because I made the mistake of thinking the right thing to do would be to lose LOS so he couldn't nuke me and the warrior could regain aggro. I actually wasn't nuking, when I should have just nuked away. It wasn't until I had given up on losing aggro and just sat and nuked searing pain that he went down. In the end I had fewer than 100 health left.

3. Let's try the Teamspeak you set up for improved communication on Terenas parties.  Perhaps we could try it out in a small party of 2 or 3 to get used to it before using it in an instance.
Let's do it again. And Blackfathom too!

It was there and I was logged into it, just nobody else was =) I forgot to log out of TS when I went to sleep and someone else logged in for a while when the servers went down for patch time.
