Guild Wars 2

Anet, please increase the contrast of some of the map markers:
(1) The difference between the icons for obtained and unobtained hero point markers is very difficult to see. Rather than having outlined green and solid green for the markers, it would be so much easier to see if they were green outlined by black for obtained, and orange outlined by black for unobtained. The outline will also distinguish it better from the background.
(2) The above/below indicators are great. Thank you. Please differentiate them more — perhaps something like blue outlined by black for one direction; yellow outlined by black for the other. This will also make it easier to see when it’s next to a harvest node (which is already green).

This is already being done for Mastery points — gray/silver for unclaimed, green for claimed. That works great. Could you take the same approach for the remaining map marker icons? With all detail the maps have, the icons with [partially] transparent interiors are very difficult to see.

they are sometimes a bit hard to see thats true, especially on dense layered maps

A good suggestion may I add that it is also extremely difficult to see where your fellow party members are one the map (specifically the minimap) as well especially if you are on different levels of the jungle floor, perhaps this can be addressed as well.
