Well, casualcolors, with an outlook like that I'd say that OP won't like any MMO that is out there, because in the end all of them can be said to be repetitive. After all you get to fight monsters over and over, but isn't that the basic mechanic behind the RPG?
Personally, I haven't found GW2 to be repetitive, there's a good variety of monsters that you encounter while you traverse the land and encounter events (yes events, there's no quests, aside from the personal story line). Plus various tasks that these events give you differ quite a bit and sometimes there's quite fun ones - like you get morphed into a panther and to complete the event you need to run around and play with panther cubs or hunt birds that are hiding in bushes.
There are very few quests that are actually about specific number of this or that (what casualcolors describes). Most of the events are centered around some goal, but can be reached by many players contributing to the same thing. So for instance there's rampaging minotaurs running through the fields and you're asked to eliminate them. There's a total counter in % that tells you how many are remaining, but the point is that you get credit for participation whether you killed 1 or you killed 100. Basically as long as you've contributed and the end goal is reached, there's no specific number that is dangling in front of you.
I do agree that like 90%-95% of the game content focuses around doing battle with your character, but on the other hand if you're looking for different content rather than battling in this type of game you're probably looking in the wrong genre. I mean repetitiveness can be attributed to the fact that you have to use your battle skills or shoot your bow over and over and over. Yeah well, that's kinda how the game works, you cannot exactly make an RPG without that, has nothing to do with WoW for that matter.
