You can’t be playing a Revenant full-time in Guild Wars 2 at this point, but the test weekends with the profession highlighted some balance issues. As a result, the designers have made some fairly sweeping changes to the profession already, starting with the introduction of a weapon swap to go along with the ability to swap between legends. Players also noted that the profession felt slow and undertuned in several areas, which is the focus of the more specific balance changes.
All of the Revenant weapons have been adjusted: staff and hammer skills have all had damage buffs, while axes and maces have had their condition application improved significantly. Players who are looking forward to playing the Revenant should examine the full rundown of the changes; the shifts and the Shiro legend will all be playable during the next public test weekend.
