Well, I'm a bit biased on this deal seeing as I'm a friend of Nara's. So, that said, the only thing I can do is tell you what I know of Nara.
First off, I can honestly say, Nara was the best DM that CM had ever had. I've personally never had any problems with her DMing, as she has the scale of justice!!!
But seriously, she's fair in her decisions.
Personality-wise, she's got an intelligent sense of humor, unlike me where I'll laugh at some of the simplest things (GOOD SHOES!!! lol)
Earlier points expressed, I do agree that it isn't fair for those who have been waiting to become a DM. The way I see it, requirements for DM (Sent, Guardian, etc) Should be based off a mix of things. Basically it should be where you check the person by:
-Time spent on the server the person would be DMing for.
-Knowledge of the DM client and how to handle issues between players.
-Responsibility with granted powers from a server owner.
-Knowledge of the players on the server.
Basically, Nara has a more accomplished understanding of the DM client from DMing on CM. She also has great responsibility with said power. Her knowledge of you guys rests solely on you, do you think she knows you decently? And Time spent is more or less moot for her.
So, that's basically it. Maybe this helped, maybe it didn't. Either way she's a boon to a server as a player or a DM.
