I did it at lvl 40 and i wont regret that a singel day of my life.. Mostly because i went male orc shamans first, but im back to females now and i enjoy every second!

Also i wanted a second boxing team wich most likley will be 1 priest and 4 warlocks! If i cba to level them past 60 i cant say for sure but to have the option to do so later is great! (and with RAF it costs me nothing realy!)
