For me, the main problems with Red are:
- Not enough people playing . . . so many dead zones
- 1 guild on server dominates everything
I started a new character on Red and was surprised how good the community has been. Haven't been PK'd once at low levels and had a nice druid port me to a better location. I've been unable to make lasting friends etc though, because there's hardly anyone playing in my level range. It's just a population issue mainly. Be fun if people I knew played. As of right now I just can't get myself to log in.
