Well, you get sprint at level 16 (note: It may actually be 15, but both weekends I tested I was out leveling and didn't train till 16). Sprint greatly speeds of traveling until you can afford a land cruiser.
If you can't get to level 16 with 4 days of playing, you probably shouldn't be putting in any type of review. It really seems like you signed up for the Beta just because you heard there was a beta to a new game without any previous knowledge of what the game is. Your complaint about dialog taking too much time is just absurd given that it's an RPG... made by Bioware, and it's been pretty much the biggest selling point on the game for the last two years. It would be equivalent to me beta testing Battlefield 4 and making a review complaining that there was too much violence.
You complain about the time per level, yet World of Warcraft used to take 4 hours a level from about 44 on (about 8 hours per lvl just to get from 56-60, when the cap was 60). They had to speed it up because they added more levels. If you expect a brand new mmorpg to get you through each zone (which has been designed and edited for the last 3 years) in the matter of 5 quests like low level Cataclysm stricken Azeroth, then the problem isn't the game you're testing, it's your expectations of a new game were based on a game that has been out for 7 years and has 85 levels, 60 of which have been in the game since the beginning.
