I've noticed DC is pretty popular too. During the beta I would have wagered AD would be the most popular. But I'm not certain the choice is based on lore.
Apparently Breton Sorcerers are a very strong class and race combination and some pick DC for that. I'm not into the min-maxing thing so I generally don't understand what they are talking about.
Another reason is that the Main Quest for EP was considered dull while AD and DC were considered fun. And with Main Quest I mean the quests associated with first big area since most beta players didn't get to play in the later areas.
It's fairly odd, all of the polls I've seen have the three factions at a rather equal rate. However, during the PTS, the Dominion was routinely dominating the PvP scene due to numbers.
It led a LOT of members to believe that Daggerfall Covenant was being groomed for the serious PvP scene (how this was concluded is beyond my comprehension).
My 0.02 is that a lot of people dislike Elves due to the whole Night Elf/Blood Elf/Legolas dynamic. Given that the Daggerfall Covenant is the only faction that does not have a true Mer race (Orcs and Bretons are half-Mer), I would say it's rather enticing to those of us who dislike Elven goofiness.

Question for those of you already in game.
Can you choose freely between the US and European mega server or is the account region bound?
You can choose which mega server you play on in the settings menu of the launcher, however I think characters are bound to a mega server but I'm not 100% sure on that.
I give the game 4/5, the combat utility seems rather bland, but not any worse then any other mmo. On the other hand crafting, exploring and overall game play is good. Only time will tell on how good the endgame will be.
Time for us all to join up together!
