I agree with the fact that the decisions you make don't have, so far, far reaching consequences.
I do prefer voice acted quests over text garbage though. I never bothered reading the quests in WoW. I tried reading quests in Rift but it was so bad and painful that I choose to ignore it eventually.
I, in SWTOR, now know what I am doing and what is happening in the world. Yes, I spacebar quests that are voiced by non-English (alien) characters, but it does add a lot to the game.
Multiplayer dialog is fun as well and the cut-scenes are fantastic. It's not just voice acting that has been added, cut-scenes also add a lot to the game.
That said, if I ever will be rolling a second toon (probably not, I leveled all classes to max in WoW before I found my main. Took me 5 years, not going through that again) I will only be doing the class quests and will PvP/Flashpoints the rest of the XP needed to advance because the class quest is only a small portion on the planets story.
