How about you stop racing to the end and at least try to enjoy the ride a tiny bit? There are a lot of senseless fetch quests in the 2.1-2.5 storyline, sure, but there's also bits and pieces of the greater picture.

There's about 20 quests between each boss trial, and for patch 2.4 and 2.5 there's also a mandatory storyline dungeon. There's ten additional optional dungeons you can unlock in Mor Dhona though, which I recommend to break things up a bit.
