All of TES series do a great job of all your encounters being randomly spread out. This is much easier due to it being single player of course but I hope there is a new twist or mechanic that is being implemented to preserve a unique feel and areas not being "zoned" for levels 10-20 for example.
I am betting all my marbles on the faction PvP that will give TESO its longevity, for me anyway. PvP always changes, is exciting, and is never static. I am eager to see how you are transitioned from your realms PvE world out into the faction PvP area, where imo, the game really will begin.
