Having played WOW for 2 years as a casual PVP/PVE player, I ordered WOLTK soon after release. Prompt delivery by Play.
The graphics are good enough for an older system to run on low settings with few bugs. The quests are adequate and the levelling is quick and easy. The achievement system is good for unlocking certain recipes/plans and gives solo players more incentives. It is nice to solo old dungeons and quests with a level 80 version of a traditional class. The new dungeons are nice and not too hard.
At level 80 the fun wears off:
A lot of professions are not profitable anymore, herbalism is one of ther few that is. The daily quests are incredibly boring and once you reach exalted and unlock a few decent items you will be wasting your time. The new dungeons and DK class dilute the skill required and appeal more to a mass market. The best gear is still only available to elitist rading Guilds or hardcore Arena players.
It would be better if all that grinding continued to improve your character to a level 100 + zone, but Blizzard wouldn't do that.
The game itself remains more for a younger audience or parents to play with their kids, but it is very time consuming.
2 stars might be a bit unfair because the game has many good points and is entertaining, however it does cost 9 quid a month per player plus the software per player. I would rather put that 9 quid towards another game, cd dvd etc.
