Anything is going to be a huge grind fest in ANY game. Though.. I do like how I actually get to eat that carrot on a stick in GW2...
I have multiple characters at 80 in GW2 and I realised it was going to be grind-fest with the introduction of Events, and how dungeons were done. (Though I like the variety of the dungeons. Instead of doing let's say.. Stormstout Brewery 5 times in a row on the same path. I could do Stormstout Brewery 5 times in a row on a completely different path, but with one or two bosses the same on the second path.)
Sadly if I was looking for a game without any sense of grinding it would be best to stop looking for one. Every game out current has a form of a grind to it. Borderlands 2, Far Cry 3, BLOPS 2, and LoL are just a few to name off. Though it's not as bad WoW's dailies from what I've been reading.
