This question already has an answer here:
Reading the GW2 wiki I found out some non-consistent data, when talking about World Completion one pages states that you don't need Hall Of Monuments zones, but the linked table lists also Eye Of The North POI for the 100% completion.
I noted also that the table is not consistent with GW2 game client, for example summing up the POIs of every map doesn't end with the current total value displayed in the game map.
The question, at last, is: is really Eye Of The North POI needed for World Completion?
If so, given the fact that only players with GW1 + Eye Of The North expansion can access it, how could a GW2 only player achieve it?
