This has been interesting to read everybody responses but most of them come down to small groups or raid parties and not giant death balls. But I feel like that is the statistically worse approach to it. The ball I was part of just ported back to the camp whenever a raid party started taking adjacent areas and just rolled over them. The only thing that stopped us was a larger raid party. Maybe its just because I main as a healer guardian but the large scale stuff just seemed really poor. Its hard to do anything for anyone when they pop in 3 seconds even when you pop a bunch of condi cleanse and drop healing all over them.
