These may max higher than 30. Me and another lvl 30 hunter were farming these for a while, conned yellow and orange but some of the oranges were real tough. Only had one call for help which was bad news since we were camped on the bridge between them all. Dirtnapping followed. I recommend that for a duo, pull from the right side of the bridge so if you get adds you got a place to run.
