Well i just made a post in the speculation thread saying what might be the proffesion, however i just found out it is infact confirmed.
The new Profession is the Guardian proffesion as revealed by PC gamer
Also people asked the PCgamer article guy via twitter if that was speculation or an early leak. He had this to say.
The third page doesnt reveal skills or anything, basically just confirming the name at this point, probably saving the skills for Anets official reveal most likely next week.
So yeah, we have our new proffesion, the Guardian
[ EDIT ]
Regina stated that the full reveal will be on Thursday the 27th of Jan, thanks to Shawn for the Link.
