Dont' think anyone can answer that for you. In the beta thread it was pretty unanimously agreed that the game opens really...poorly. My personal thought is that the game doesn't seem like it does anything fresh at all when you're just standing there hitting 1 and 2 on the early 'easy' mobs. Even the Giantbomb quick look is pretty funny since Brad JUST started getting to the part where you have to pay the most remote attention to the game and kept dying, but had been saying it was easy so far heh. I had to play the beta several times over 6 months or so to finally get into the teens and start having a lot of fun killing mobs. Questing is dry if you force yourself to do every tedious task - but they're clearly labelled as tasks here, so once you realize you can skip those if you want and you'll be levelling just fine it helps a lot. There are a LOT of really creative and fun quests past 20-25ish, and a lot of boring standard shit like every other MMO of course.

Forgemaster in Kel'Voreth is probably worth a Youtube as well - there are lots of non-visual mechanics you might miss on both too, but that's alright would give you an idea of what the game is like. If it seems appealing go for it, nothing else really has combat experiences quite like that, but I would say aside from that and solid housing the rest is fairly standardish.
I'd agree with whoever said it gets progressively better in every zone up there, with the possible exception of Wilderrun in 35-40.
