How do i enter lvl 80 maps?
For the maps, are you meaning the Silverwastes and Dry Top (there are other level 80 maps, but these ones may be the least apparent for getting into)?
It would help if you let us know what level 80 areas you are looking at. The ones that I know of…Southsun Cove, is accessed through a portal in Lion’s Arch. I think it is now located with the other portals. Dry top and Silverwastes are accessed through Brisban Wildlands. Frostgorge Sound is not strictly level 80…but goes up to 80 – accessed through northern Wayfarer Foothills or through Northwest Fireheart Rise. Then there are the Orr zones…I am thinking that Cursed Shore is the only one that is strictly level 80. Those are all accessed sequentially starting down in either Mount Maelstrom or Sparkfly Fen. Not sure if this helps or not.
As to the other question about key binds…I have not found a way to have different keybinds on different characters. They seem account bound…but others might have better insight into that.
I assume you mean the new maps. Go to Brisbane. For Silverwastes, go through Fort Vandal near the south west border. There is a portal there. For Dry Top, keep going south west. At the south west corner of the map is another portal.
Weapons/key binding. There are no character specific key binds.
ANet may give it to you.
For the zones, see posts above.
For different class key bindings, technically not doable in game. If you have a gaming mouse or keyboard, you could use macros; just set them to press a specific key and swap them out when you change classes. Since it’s still 1 press for 1 action, it’s completely legal.
