Guild Wars 2

Just returning to the game after taking a few months off, and noticed that three achievements have been added to the boss tab – the 3 heads of the Great Jungle Wurm. I already have Wurm Decapitator and Wurmslayer, so wouldn’t I automatically get the three new achievements for defeating the wurm? or are the achievements not retroactive?

They are not retroactive. They were new achievements added with HoT when it launched for players to work towards in order to gain additional mastery points

Thanks for the info
