Curious. Are you maybe trying to down all the mobs? The vets and normal mobs can cost you precious time. I've been involved in two successful and one failed capture now. There wasn't anything special about the successful groups, both were PUG groups, no voice coms, one a group of five and the other of six. All we did was get to the spawn as fast a possible and then focused on the canids (icon overhead) and then the champ, repeat until dead and wait for the next spawn. We got knocked around plenty but managed each spawn with 10-30 seconds left. The last fight was one legendary that was easier to down than the champ groups. Classes for the successful groups:Group 1: 2 Dragon Hunters, 2 Scourge, 1 Weaver, and 1 Soul Beast.Group 2: 2 Dragon Hunters, 2 Berserkers, and 1 Scourge. I can't speak for the others setups but I just went to metabattle, took a raid build and tweaked a bit to my liking. For what it's worth .. the failed group was a four man of 2 Dragon Hunters, 1 Weaver, and 1 Soul Beast.
