i've been looking for a map addon thats just like the topic add locations to the map for the instances and stuff no Cartog3 that makes everything load slow as in realllllly slow

Cartographer3 is an experimental addon and should be treated as such. As ar as instance locations, once you go there once do you really need to know where it is in the future? I realize that in Wrath a lot of stuff is confusing for all of us but just like TBC once you have been to Ramps you know just where to go every time. It's not like they change the location of the instance. BTW, on the maps (default even) each instance is marked by the name of said instance. Cartographer shows information about what is where when you hover over each zone when you are zoomed out too.

For instance look at the map for Grizzly Hills, Drak'Tharon Keep seems pretty well marked in the upper left of the map. Check out this link for locations of each instance by continent: http://www.wowwiki.com/Instances_by_continent
