A new profession has been announced: the Guardian
. Essentially, it can be compared to the role of a Paladin in other MMO's, and comes closest to the Monk in the original Guild Wars. These days, however, MMO developers try new things with healing classes, trying to address the problems that a strictly healing class have posed. The Guardian offers a solution by essentially making him/her the Warrior/Monk combination, setting its healing skills to optional and focusing more on Wards and Spirit Weapons.
The above video is obviously dramatized, but is in-engine and shows some great skills.
In any case, it seems most Guild Wars veteran players are waiting for a Mesmer class announcement, which is understandable, of course. The Mesmer was loads of fun to play and a valued asset in PvP.
