Guild Wars 2

My character is getting closer to lvl cap -72 right now.
I would like to go to Frostgorge Sound which will take me to 80 w/o changing zones
again. Anyone has an advice on how can i get there the easiest way.
I never been in Wayfarer Foothills which i know has a gate to it. So the question is how i get to W.Foothills and than where is the gate to Frostgorge in that zone?
By the way what could be the reason that these zones are so scattered w/o any logic?
Some would come in mathematical sucsession like 10-20-30 but others are bordered like Frostgorge(70-80) by 1-15 and 15-25 and 40-45.
The other thing i am wondering why are these gates so hard to find?
Look i am not criticizing the game i liked it so far i am dealing with the difficulties just
like the rest. Maybe there are good reasons. I am just asking some questions.
Anyway please help me finding my way to W. Foothills/Frostgorge. I am presently in Straits of Devastation.

Well I don’t know where the Straits are, I’ll assume Orr, but the best way to go would probably be from Hoelbrak. Take Wayfarer Foothills all the way to its NE corner and there’s a portal to Frostgorge there.

For ascending zone-levels, most of them generally converge in the middle and move south. The glaring exception to this is the Charr lands where the eastern zone-levels ascend as you go up and around counter-clockwise and stop at Frostgorge. Not sure why that is. /shrugs
