I'll come clean, I'm not a MMO guru. Not at all. I've also got not much interest in the others in the field (WoW for example). A friend recommended GW to me, as a change from the FPS rut I was in, and I really liked the laid back pace, the exploration and satisfying progression. Plus, it was an easy way to get coop action with chums, as this seems to be on a par with quantum mechanics for FPS devs.
This term "grinding" seems too negative a term to me, but then maybe this is my subjectivity talking. What you see as, what I presume from the inflection, a chore, I see as progression. Conversely, I get not real sense of progression from the PvP aspects of the game.
Maybe Anet want a different audience than me, maybe they will get that audience as well. However, unless some sort of effort is given to the PvE aspect of the game, I'm probably going to have to pass this time around.
