With the recent server transfers made available to Warhammer Online players, Mythic enabled players to move onto several servers free of charge. Now they're offering limited time server bonuses for players making their trek onto the offered servers. The bonus itself is a 20% rested boost to experience and renown gain. It's a nice little cherry on top for players packing their bags and it should also help encourage some people on the fence to take Mythic up on the offer.
Anyone interested in making a move (or seeing if they're even able to do so) can check out this handy list at their leisure. Massively is sure to see more of this kind of encouragement from Mythic in the future, at least where and when it's necessary.
