No matter how good or bad the game is, the community is freaking amazing.

You would greatly limit your experience in GW2 if not for other players. So that is a false premise saying that it is the least dependency on other players. I know you have played the game but you haven't really played it other than as a casual leveling experience. Games like SWTOR are far more solo than GW2 is. Just because you don't formally group up for non instance events in GW2 doesn't mean that you don't depend on other players.

I do various instances with groups. Fractals, raids, dungeons, the living story missions or whatever they are called. Et cetera.

I don't think I've ever played an mmo where other players didn't feel like 'more active npc's' unless approached otherwise
