In AK, it's possible to break the encounter with Hadronox by having a character run past the spider and use one of a number of defensive abilities to make it to the hole at the bottom of the spider web while maintaining his attention. Hadronox will not be able to follow and will wait at the edge while the rest of the group walks by, slaps him on the behind and says "good game, sport." Many groups are using this to skip the encounter.

I'm not much a fan of bypassing an easy fight for the convenience of 1-2min of time for those who are clearly overgeared to go sit in Dalaran or Org/SW. I've been sworn at enough times over it, so I'm reporting it.
