More of the same as expansion runs out of ideas
Firstly, set in a zone that players already have(Eastern Plaguelands), the Litch King expansion clearly proves that Blizzard have run out of ideas. Quests are the traditional pointless 'go and kill me 20 of xxx' and the totally boring story of the Litch King means that as the new Death Knight class, you must complete all the tedious quests first, before setting off to your Alliance/Horde locations.
Personally, I would love to see pvp improved upon but this was a missed opportunity as the expansion introduces a new profession - Inscription to the game. At least players now get the chance to customise their abilities more.
Overall, this is just another lazy attempt with all the old stuff being recycled into new with different colours. Its about time Blizzard woke up and kicked their minions into be more creative.
