There is no content in this game that you need to grind gear for, except for one single dungeon, and the gear you need for that dungeon is found in that dungeon. That's not what people mean when they say gear grind.
Have you ever played an MMO that locked you out of instances completely because you didn't have the right stats? Rift does that. Want to do this dungeon? No worries. But you'd better make sure you have the right amount of focus or you can't queue for it.
Guild Wars 1 had plenty of grind too...but it was voluntary. The same can be said for Guild Wars 2.
