Guild Wars 2

I want to get specialization for all 8 of my classes right after HoT.

I’m deciding whether I should go do more Hero Challenges base on how many Hero Points per Specialization. (This is including unlock all new skills)

Any news on such matter?

No.

Just that there will be Hero Challenges, or some way, to obtain Hero Points in the Heart of Maguuma.

There’s a big thread on this exact thing two threads down on the HoT page
