Any dps class i lvl by just having a healer tag along behind them and letting them run wild... I also have a mage at ea 10 lvls starting at 20..(20 30 40 50 60 70) allows me to 3 box.. healing and dps with the pled char getting full solo xp (out of grp). Normally takes just under 5 days played per char to 70 (and that's not pushing it, Im too old to stay up 3 or 4 days straight to see how fast i could make it happen).
