The game is what you make it, basically. If it's nothing but a "constant gear grind" it's because you're making it that, in my opinion. Sometimes I like to just run around and see if I can find places I haven't been to before. Sometimes I like to go help lowbies do quests or something. Sometimes I like running dungeons and sometimes I like doing PVP. But in general, if I find that I'm not having fun doing something, I'll stop doing it and do something else.
