Exploring the Arenas for 100%

I'm currently stuck at 99.6% explored of Tyria.

I'v been exploring everything there is to explore, exept from the 2 old Arenas, 1 in Ascalon lvl 1-10, 1 in The Shiverpeaks, Yak's Bend lvl 1-15. Wich i can't enter since i'm lvl 20, simply enough. They are somehow shadowed in some corners and not fully explored it seems.

Doing Random Arena from the battleislands don't seem to help it either, allthough i can fight in thoes 2 then ofcourse.

So i wonder, do this add to the 100% of the map? Or have i missed some spot

Core Areas on the Battle Isles do NOT add to any campaign map %. You need to go back and look and see what spots you have missed.
