Is it possible nowadays to learn old proffesions? In Istan we can see dervishes and paragons. Some of them use even skills from GW1. For example Spearmarshal Zaeim who use song of power and anthem of flame. Are those skills as effective as 250 years ago?
And what about Livia. In living story she is using a hex. In Guild Wars 2 she was a necromancer and now she had skill named "Fragility". Is this the same spell as mesmer's Fragility in GW1? If it is, she could change her profession or keep the second one? There is still place in GW2 for hexes, beacause if i'm not wrong, Livia, for us, is the only example of person who used hex so far.
