You are among the first of many to discover a Wrath of the Lich King realm like no other. We've started out with a basic idea of launching pure-blizzlike, but thought about what could make the already-great expansion even more enjoyable to play in this new day and age.
We've decided to improve several areas of the game, including battlegrounds and arena rewards. As well as many quality-of-life changes that only improve your gaming experience without removing anything at the sametime. For example, all flying mounts are now dynamic and can be used in anywhere, changing depending on your location. You may also purchase a Flight Master's License and unlock flying in Eastern Kingdoms and Kalimdor, excluding major cities.
You may read a full detailed post on all of these improvements and rewards here. You can view raid and dungeon development progress here!
