I'd still like to see some kind of bonus, tied in to lower level FR content, that relates TRing to the Destinies, to Epic xp. Some way to synergize between TR and Epic levels, in order to tie them together.
Maybe it's as simple as an xp bonus, or something cosmetic, but these things are more fun when there are synergies.
For example, there could be a tough level 25 quest, that upon completion, opens up a feat called Old Soul. And if you have that feat when you TR, there could be new lower level FR quests, that when you complete some difficult optional, you get a bonus to your epic xp that life (something modest, but appropriate) and/or something cosmetic.
We just want something to work towards and for that something to be well thought-out and fun. I prefer when mechanics are synergized and fun with good content design, rather than an obvious add-on.
