I don't think it's unreasonable at this point that players who preordered ARR should get one additional month of free service after all these problems are sorted out.
Actually on reflection I think this would be a bad idea. One of the problems is the freeloaders who preordered the game for access codes, canceled their preorders once they downloaded the game and activated their code, and are now congesting the servers without having spent one penny to support the game. The sooner the free trial period ends and these players leave the better. Some of them are 1.0 players without Legacy status who probably felt justified doing this, but many never even bought the game.
This could have been avoided if early access had been tied to the CE instead of a preorder bonus, with an early access code in the box and a separate ship date for the CE and regular editions.
