Pretty much depends on the server. On Raid Addicts all 16 Classes are balanced so you can pick what you would have picked on Live.. The same can be said about PEQ.. and many other servers.. But then there are servers that are custom (wannabe) and they only have maybe 3 or 4 classes that are any good..
Seen servers where only Monks and Warriors were good the rest were useless.. Just depends on where your at
