Being able to swap around these legendaries to unlock new strategic options to tailor your character for specific situations. This is not to say that the utility legendaries will be required for such content, just that they provide an additional layer of strategic depth.Of course, for that first legendary when you're really hoping for that straight-up DPS increase, we realise it's disappointing to get one of the utility ones. We realise that some of the utility legendaries aren't very attractive right now and we have some tuning, or in a few cases, potential re-designs, aimed at those legendaries in the future.Also, grats on your legendary - I still don't have one!I see what you're saying, but on the flipside we're not even 2 months into Legion yet. I get that not having a legendary, or having a less than ideal one, is pretty frustrating at the moment. But, zooming out a bit to look at things in the long-term, by the time we are say... 10+ months... in, it is very likely that most players who have been playing regularly will have more than 1 legendary at their disposal.Like I said, we recognise that some of the more utility orientated legendaries aren't great right now, and those are under review to give them a little bit more razzmatazz. At this point in time I don't have anything more specific I can share. ( Blue Tracker Artifact Knowledge has a cap which is rank 25. So eventually, people who play regularly - regardless of when they started - will all reach the same rank of Artifact Knowledge.Right now the research time for the lower ranks of Artifact Knowledge is lower than those who've been researching since the first week of Legion.We do realise that later into the expansion this might not be enough for alts, or newcomers, and we are considering some options for other catch-up mechanics to be added later down the line.
