OK Here's what happened.
Dragonhawk boss in Zul'Aman. Boss summons egg hatchers. I run over and drop a Frost trap in the hallway. Shortly after my trap disappears without the AoE slick, or the slowing effect. This has not happened before, so I am curious if it was because of our brief change.
Normally we have a druid tanking the hatched dragonhawks. This time we had a pally tanking the adds and casting his AoE... I can't remember the name of the spell.
Is it possible that it was a glitch or do you think it was designed that way?
