To be done at cap:
3x Impossible Demands (E, H, N).
4x Two Toad Tobias (R1, E, H, N).
4x Lost at Sea (R1, E, H, N).
3x Lords of Dust (E, H, N).
4x Subversion (R1, E, H, N).
4x Grim and Barett (R1, E, H, N).
This will give 44 Heart Seeds so could drop 1 run if you wanted to or keep it to save up each time. Could probably have it all done in like a couple of hours or so depending on build etc.
I've found that having 3-4 capped characters(first life, no tomes, no raid gear) and doing the 5 shortest quests in KotB is best. I haven't timed it out yet but it feels like it takes maybe 20 minutes to pull 10 seeds. I know those quests are faster by far than most others.
