Can you tell us which quests?
An absolute bucket-load of them.
I noticed that almost every quest (except dailies) from Weeping Cast onward have had the XP & TP increased.
The main giveaway here is that up to Aotulia Volcano, most quests gave the same XP/TP reward as the dailies in the zone. The dailies still give the same XP/TP, but the regular quests give significantly more.
Quests in Thunderhoof Hills and beyond gave slightly-higher XP&TP than dailies, but they have also changed quite a bit.
