Right now, my biggest issue with the game is the pre-order bonus. Allowing people to use any race within any faction is horrendously lore-breaking, more so than anything else they've done so far. Considering how many people pre-order games, there will be enough characters in factions they dont belong in that there will be no reason to have separated the races to begin with. My immersion was ruined before I ever played the game.
And good look quickly determining who to attack in PvP.
