Playability
When HoT releases will you be able to play it at lvl 80, when you do personal story or when you complete all of Season 2? Or will it be all of the above?
As soon as you hit level 80 you will be able to play any Season 2 episode and what comes after (That is The expansion), if you have bought them that is.
So like it would be realy bad against players who buy HoT now they will have HoT but cant play it becouse they havent bought the Season two episodes :P Nah, you will be able to play HoT as soon as you are level 80 as then you will Unlock the first story for the Expansion that will take you to Verdant Brink.
This is no Fact though. I have no source.

There are no requirements, other than purchase and the fact that these will be L80 maps. You could enter with a lower-level, but depending on how low-level, you might find the content quite difficult.
Good luck.
