Mostly good, but Gjally should be left alone. For the record, I did all my hard work without it, as it finally dropped for me this week when I chopped up Crota on HM. Still, it's nice to have something that makes all that time spent feel worth it. Destiny is a major grind, and after Gjally dropped for me it's a tad bit easier. That's how it should be. Otherwise, if grinding doesn't lead to better weapons and more fun, why keep playing?
