I've used Macrogoblin for a couple of weeks on GW2 and it works fine. I never liked this type of bot for playing WoW or SWTOR, but it works well for GW2. There are events going on all the time in the zone, and there is no need to pick up quests since your character simply walks into the events. This makes a bread crumb bot like Macrogoblin the perfect bot for GW2.
