You only need to grind them if you're dedicated raider afraid that someone may find you without a perfect LI.
I LOLed. While I don't share your view of LIs (I do try to make mine the best I can), there is a lot of truth to this jest.

While I do think complaints of grind-ishness are well founded (if you want certain things you really have no choice but to grind for them), I do feel that to a large degree, grinding is in the eye of the beholder. For me, if I want something, grinding to get it is enjoyable, because I am working toward a goal. For example (and I know a lot of people are going to think this is crazy), I love doing slayer deeds for virtues. It's satisfying to get them all done, I get a lot of gold and rep items doing them, and I find the process meditative and relaxing. However, Hytbold was painful and something I will only ever do once, on my main. It's highly unlikely I'd ever grind that godforsaken town ever again (they REALLY need to lower the token requirements of the rebuild quests to make this more rewarding and enjoyable). But then what do you get out of completing Hytbold? A couple titles. Most anticlimactic content of all time. A set of war-steed cosmetics or a unique and awesome housing item would have been appreciated... I digress... Yeah, grinding is a highly subjective thing.
