Hello Droidz. Same problem here, the char takes 30 sec to turn to the target. Can you please help?!
Edit: Problem solved. The monitor and the game need to run at the same refresh rate. And while WoW can only run in windowed mode in 60Hz refresh rate, if you are using a monitor with a refresh rate higher than 60Hz, it won't work properly. Set your monitor to 60Hz aswell (in windows) and check Vertical Sync in wow/menu/video and it will work. Or at least it solved the problem for me and some others (i read about the solution on a forum, not my idea).
