I'm not sure how possible this is so bear with me.
How great would it be though, if someone like me could just click Epic 2.0 Prereqs for Scouts or Fighters or Priests or Mages and just have it go?
Stay with me. I have so many toons and it's very time consuming to know what I have done and haven't done on them. RQ pretty much already does this where it searches your journal for what you've done when you start a timeline.
How great would it be if I was to hit Epic 2.0 Prereqs for Scouts. It searches Kunark Ascending, see's I'm finished. Then searches Order of the Rime and see's i'm not. Starts Order of the Rime. Presumably finishes Order of the Rime, then searches for KUrn's Tower Access. See's I've done that so searches for Cobalt Scar and sees I need a few quests in that to finish.
Even at minimum, having the RQ show Epic 2.0 pre-reqs and then have that broken down by type would be helpful.
Click Epic 2.0 pre-reqs > Click Scout / Fighter / Priest / Mage > Display the pre-reqs that are relevant for the archtype.
