What is the most/least common class/race around this here server ya'll are runnin'?

Most common is rogue.

As far as least common, there are a few I see.

Pure fighter Pure ranger Pure barbarian Bard

As for the warrior classes, people tend to multiclass them most of the time. Fighter/Rogue has become a pretty cliche class overall. I'd like ot see more pure builds instead of clones of the same build.
