It has been asked for so long, but sadly unanswered: The Survey system in ESO is extremely time-consuming and it is also extremely clunky imbedded.
Right now stacked resource surveys can only be harvested by finishing one and then either riding away and coming back an unspecified distance or by porting out and back in. Also resource surveys can cluttering our inventory and are becoming more and more with each released chapter.
I have a few suggestions:
1.) Add the Survey maps to the ESO+ Crafting Bag to reduce the strain on our inventory
2.) When harvesting a FULL survey area, make it respawn immediately if you still have a survey map in your inventory.
3.) Put the different nodes in each survey area closer together where applicable. Currently nodes in High Isle are the most far away from each other i have ever seen.
Please, don't let another huge patch go live without adressing the Surveys!
