In Diablo 3, there is an affix called "Wormhole" that causes you to be moved from one side of a pink circle to another after a second or two of delay.
This seems to be by far the most benign monster affix! Who cares if you get shifted from one spot to another? More often than not, it actually takes me out of a dangerous floor covered in fire or acid. Am I missing some hidden danger here? Are there some classes and playstyles that are actually threatened by this affix?
See this for reference.
