I think Hitoo described a good TU build, altough at lower level you can sacrifice a little int and stop at like 75~80 to raise your dex (cast time) faster. Aside from that, priest are definatly a class that can be leveled fast. And aco is also one of the fastest first class to level (firelock + heal + pneuma).
I do see some people party for real, and I appreciate that not everyone is running solo. I'm still working on the january patch, I'll see if I have time to disable dual-clienting.
