Guild Wars 2

So can we play the HoT story when we not have done first the personal story?

Thats a nice thing to know because I will be one of the guys who power levels his Revenant straight to lvl 80 and wants to play the new story.

Hello community and maybe developer.
I have read it from some people that it will be nice to play the Revenant before the official release of HoT on the main account and start like a week earlier to bring him to lvl 80 doing the Personel Story and some other Stuff to start with all other Players right at the Launch of HoT and play the new content.

So developer are they any plans to do this and how many from the community would that want too?
