Yeah, the only time it's really a problem is when the entire other team is strikers and blade dancers, that's when it's the biggest problem. Especially when they are in a fireteam, able to communicate with each other. I had just ABYSMAL luck last night where every time I got into the Crucible, there was a group of 4+ people all using thorn, felwinter's, or something similar. It was seriously frustrating, even if I left and joined another round I was paired up against another team.
