I'm a PvE'er who doesn't particularly like WvW. I find it repetitive and boring although I've met many great players there. It's just not my style. That said, I'm working on my 4th Legendary Weapon so the Gifts of Battle are a necessity and I've put in the time to get them. I do one or two dailies per day, easy points, and run around the Borderlands with my guild once in a while on weekends. It takes me a long time to get a GoB, but I'm farming everything else I need for a Legendary too, so what's the rush?
As others have said: If you want a Legendary, either put in the time and effort to get the components, or buy it off the TP.
