The sagas are a nice addition, kudos on getting them out. However, the current status of them should be more easily available. Please add the list from the saga questgivers to quest journal, or some other place you can check without going through all the questgivers.
Tracking the completions on one toon is hard enough, but with several, it's impossible. Currently the only solution is either to visit every saga giver at the start of each session or to keep an offline spreadsheet (be it paper or an actual spreadsheet). To me that is just unacceptable, taking the user experience decades back.
Kudos on the tracking list on saga givers, it's almost perfect. Just add Heroic/epic to it and it's good. If the list was updated from Normal: list, Hard: list, Elite: list to Heroic/Epic Normal: list, Heroic/Epic Hard: list, Heroic/Epic Elite: list, it would be awesome. As the heroic and epic saga dudes are intermingled, it's a bit annoying not to see whether the questlist you are currently checking is heroic or epic.
But, the main part, make those lists available without visiting the saga dudes and life's good. Even better if those are in one spot, the Quest Journal is one possibility, some other places might work as well. Regardless, it would be nice to have all the sagas in one place, such as a new area called Sagas in the Quest Journal.
