I think that threnals are a great pack of 9 quests. I really like em except for one thing: the xp on east 3. It is so bad xp/min that i dont run threnals more or less on my TR:s.

My suggestion is that timed quests (east 15 min) shall give xp as other quests of that lvl range that takes around 15 min, if you say that a flowerpicking pace is 500xp/ min and a good pace is 1000xp/min maybe a base xp of around 6000xp or so for this quest are more reasonable. Count in that this quest also are a tad risky you can fail it, that would also count for some bonus xp cause of the risk.

15 min risk quest for 500xp ie like 30xp a min when you can run von 3 for 1500xp/min aint balanced imho.

(But for the love of all do not nerf xps in von 3 and wizking etc, boost lover xp quests!!!) (and east 3 are the worst example- a quest that more or less lock you out from playing 8 other quests if you TRing)
