Took down 2 of these tonight as MT for a full group using my 61 beasty. The first dropped a parchment and the second dropped me. Yes, the rats seem to like these skeeters and will follow them into battle. Didnt even see the rats till they had eaten our cleric. Skeeter sent misc toons in random directions just long enough to be long enough.:)
Still worth the parch, but definately underconned.
